A 1-yuan coin worth 7,800 yuan, stored in an old piggy bank at home or hidden away, with few owners.

Today, I want to talk about a coin that can be called the “Low-Key Dark Horse of Collectible Coins”—it’s not Yuan Dàtóu, not the Great Qing Silver Coin, but a 1 Yuan coin that many post-70s and post-80s grew up holding and using, yet never paid much attention to. Now, a well-preserved specimen can sell for up to 7,800 yuan, a 7,800-fold increase!

Many people might find it hard to believe: “A 1 Yuan coin worth 7,800 yuan? I think I have several of these in my old wallet or piggy bank, just sitting there as ordinary old coins, never giving them a second look.” Some younger collectors might even be curious: “What kind of 1 Yuan coin is this? Why has its value increased so much? How is it different from the current Peony or Chrysanthemum 1 Yuan coins?”

Honestly, this coin is the China Reform and Opening-up era’s first issued coin—the Great Wall 1 Yuan coin. As the first truly modern circulating 1 Yuan coin in Chinese history, it carries the memories of the 1980s. Its short issuance period and limited quantity make it especially rare, particularly the 1980 brick-version in good condition, which is a favorite among collectors. Experts say: owning one of these is extremely rare.

In this article, I will use straightforward language, combined with over a decade of practical experience in coin collecting, to thoroughly explain this “7,800 Yuan 1 Yuan coin.” No complicated jargon—just detailed background, authentic features, key differences between brick and non-brick versions from 1980, valuation, and practical tips for collecting and preservation.

Whether you’re an older collector who experienced the 1980s and has similar coins, or a beginner looking for a good deal, you must read carefully. Especially if you have old coins, piggy banks, or drawers at home—perhaps the coin you casually set aside is a potential “hot item” worth 7,800 yuan. Missing out would be a real loss! Let’s start from the beginning and revisit this coin that bears the mark of its era and has quietly appreciated in value.

1. Introduction to the Great Wall 1 Yuan Coin: The “Hard Currency” of the 1980s, Embodying a Generation’s Youth and Everyday Life

Before diving into this coin, let’s clarify some key questions collectors care about: When was the Great Wall 1 Yuan coin issued? Why is it called the “Great Wall coin”? How strong was the purchasing power of 1 Yuan back then? How does it differ from today’s 1 Yuan coins? Why did it gradually exit circulation and become so rare, even fetching 7,800 yuan?

Many newcomers see the words “Great Wall 1 Yuan” and immediately think: “It must have a picture of the Great Wall.” Correct—the front of the coin features a clear image of the Great Wall, which is the origin of its name. But what many don’t realize is that the Great Wall 1 Yuan coin is part of China’s “Great Wall series of circulation coins,” which includes 5 Jiao, 2 Jiao, and 1 Jiao denominations, issued to meet the small-value payment needs of that time.

Let’s review its background: In the 1980s, China was just emerging from the initial phase of reform and opening-up. The economy was recovering, commodity circulation was increasing, and small transactions became more frequent. At that time, the main circulating currency was paper money and a small number of older coin versions. While paper bills were convenient, they tore easily and wrinkled with repeated use, making change less convenient. The older fractional coins had too small a denomination to meet the 1 Yuan payment needs, creating an urgent demand for a durable, moderate-value coin.

To meet this demand, China began planning the issuance of the Great Wall series of circulating coins in 1979, jointly minted by Shenyang and Shanghai mints. The full set included 1 Yuan (with a Great Wall design), 5 Jiao (plum blossom), 2 Jiao (wheat and gear), and 1 Jiao (wheat and gear). This formed a complete small-value currency system, with the 1 Yuan coin as the main component, and it was the most common coin in circulation at the time.

The Great Wall 1 Yuan coin was issued from 1979 to 1986, with a total of 7 different years: 1979, 1980, 1981, 1982, 1983, 1984, 1985, and 1986 (note: 1979 was only in packaging, not circulation). While the coins look similar across years, their mintage, circulation, and preservation vary greatly. Only four years—1980, 1981, 1983, and 1985—truly entered circulation, with the 1980 brick-version in good condition being especially valuable, reaching up to 7,800 yuan.

Many collectors who experienced the 1980s recall their youth: holding a heavy Great Wall 1 Yuan coin, with its cool, metallic feel of copper-nickel alloy—completely different from the lightness of paper money. The fine serrations along the edge and the slight friction when passing fingers over the edges evoke a sense of durability. Back then, this coin’s purchasing power far exceeded today’s, making it a true “hard currency.”

You might wonder: how much was 1 Yuan worth in 1980? Today, 1 Yuan can hardly buy anything—maybe a bottle of water. But in 1980, 1 Yuan could cover a family’s small daily needs. Based on historical records and memories of older generations, let’s explore what that meant:

• 1980: 1 Yuan could buy 2 Jin of rice—at about 0.45-0.5 Yuan per Jin—enough for a meal for a family, or even two if saved carefully.
• 1980: 1 Yuan could take over a dozen bus rides—bus tickets cost about 1 Jiao, so a single Yuan could buy multiple round trips.
• 1980: 1 Yuan could buy 5 fried dough sticks and 2 bowls of soy milk—each fried dough stick costing about 7 Fen, soy milk 5 Fen, totaling 4.5 Fen for five sticks and two bowls, enough for a hearty breakfast for a family of three.
• 1980: 1 Yuan could buy 10 ice pops—each about 1 Fen—perfect for summer snacks.
• 1980: 1 Yuan could buy 5 children’s storybooks—priced around 15-20 Fen each, providing entertainment for childhood.
• 1980: 1 Yuan could buy a bottle of white liquor and a pack of cigarettes—costing about 80 Fen and 20 Fen respectively, a common leisure combo.

Additionally, postage for a letter was 8 Fen, so 1 Yuan could send 12 letters with 4 Fen change; a Jin of fresh vegetables cost 2-3 Fen, so 1 Yuan could buy over 30 Jin of vegetables; a pair of cloth shoes cost about 1.5 Yuan, so 1 Yuan could almost buy half a pair. These examples show how strong the 1980 Yuan’s purchasing power was.

From a gold value perspective, in 1980, gold was about 30-35 Yuan per gram. So, 1 Yuan was worth roughly 0.028–0.033 grams of gold—seemingly insignificant. But in daily life, this small coin could solve many practical problems, making it a true “hard currency.”

Today, gold prices have soared to over 500 Yuan per gram. The 0.03 grams of gold that 1 Yuan represented back then is now worth about 15 Yuan. Yet, a well-preserved 1980 brick-version Great Wall 1 Yuan coin can fetch 7,800 Yuan—equivalent to about 15.6 grams of gold, over 500 times its original gold value. Such appreciation is considered a “miracle” in the coin collecting world.

In the 1980s, the Great Wall 1 Yuan coin was everywhere—full of life and local flavor: shopkeepers at markets, children buying snacks or stationery, bus passengers dropping coins into fare boxes, post office transactions, and street vendors giving change—all used this coin. Its material was copper-nickel alloy, also called “white copper,” common in the 1980s Chinese minting industry, quite different from today’s aluminum-magnesium or steel with nickel plating coins. Copper-nickel is hard, wear-resistant, corrosion-resistant, with a cool, weighty feel—far superior to the lightweight, less substantial current coins.

Thanks to its copper-nickel composition, even after over 40 years, if well preserved, the coin can remain in excellent condition, with clear patterns and a warm luster—one reason it can fetch high prices. In contrast, modern coins like Peony or Chrysanthemum series, made of aluminum-magnesium alloys or steel with nickel plating, are more prone to wear and oxidation, reducing their collectible value.

2. Why Has This Coin Become So Rare and Valuable Despite Its Commonness in the 1980s?

The main reasons are threefold:

• Short issuance period and high circulation consumption: The coin was only issued from 1979 to 1986, with most years having limited mintage. Many early coins—especially from 1979, 1982, 1984, and 1986—were mainly used for packaging, gifts, or collections, with few entering circulation. Being a 1 Yuan denomination, it was used repeatedly, leading to wear, loss, or destruction. After four decades, many are heavily worn or destroyed, leaving only a few well-preserved specimens.

• Early exit from circulation and decreasing survival rate: After 1986, with the introduction of the Peony series, the Great Wall coins gradually phased out of daily use. Over time, most were collected, melted down, or lost. The remaining genuine coins are increasingly scarce, especially in good condition, making them highly valuable.

• Low awareness and overlooked genuine coins: Many households still have old coins in wallets, drawers, or piggy banks, but they often dismiss these as ordinary old coins, unaware of their potential value. Many are discarded or used as toys, missing the chance to preserve rare collectibles. As a result, genuine coins are becoming rarer, and those remaining are mostly in the hands of seasoned collectors, pushing prices higher.

Among all 1980 coins, the brick-version is the most valuable, especially in good condition, reaching up to 7,800 yuan. The key reason is the difference between “brick” and “non-brick” versions—fewer brick versions were issued, making them more scarce and valuable. Next, I will explain how to distinguish these two versions and avoid missing out on high-value specimens.

3. Key Differences: Brick vs. Non-Brick 1980 Great Wall 1 Yuan Coins—A Critical Distinction

Many collectors don’t realize that although 1980-issued coins look similar, there’s a subtle detail: some have a brick pattern under the Great Wall image, while others are smooth in that area. In coin collecting circles, these are called “brick version” and “non-brick version.”

Some might think: “It’s just a tiny brick pattern; does it really matter? It doesn’t affect usage, so why does it impact value?” Actually, in the collecting world, “details determine value.” Even a small difference in mold or craftsmanship can cause a price gap of several times, or even hundreds.

For the 1980 Great Wall coin, the brick version and non-brick version are identical in denomination, material, and size, and can be used interchangeably in daily transactions. But in terms of collection value, the difference is huge: the non-brick version typically sells for 500–800 yuan, with excellent specimens reaching 1,500–2,000 yuan; the brick version, however, can fetch 2,000–3,000 yuan, and top-quality graded specimens (67 points) can reach 7,800 yuan—over four times more. This is why collectors must carefully check whether their coin is a brick version to avoid undervaluing or overpaying.

4. How to Quickly Distinguish Brick from Non-Brick Versions? (A Must-Know for Beginners)

Many newcomers worry: “The brick pattern is so tiny; I can’t tell the difference. What if I get it wrong?” Actually, distinguishing these two is quite simple with two quick tips:

• Tip 1: Check the position carefully. The brick pattern appears in a fixed spot: under the “fire beacon” on the city wall, in the middle area between the wall and the mountain. Under good lighting and with a magnifier, you can see: the brick version has a clear, rectangular brick pattern, while the non-brick version is smooth without any pattern.

• Tip 2: Use tools for precise identification. If you find it hard to see with the naked eye, use a magnifying glass (10x or higher). Examine the area under the fire beacon: the brick version shows a distinct, textured brick pattern with clear edges; the non-brick version’s area is smooth, with no pattern, making it easy to tell.

Beware: some unscrupulous sellers may artificially engrave brick patterns onto non-brick coins to inflate prices. These artificially added patterns are rough, uneven, and lack the regularity of genuine moldings. Touch and examine carefully—if the pattern feels rough or inconsistent, it’s likely fake.

5. In-Depth Analysis: Authentic Features of the Great Wall 1 Yuan Coin—How to Avoid Fakes and Pitfalls

As the coin’s value rises, counterfeit versions increase too, with varying quality—from rough imitations to nearly indistinguishable high-quality fakes. Many collectors, especially beginners, risk paying high prices for fakes or mistaking genuine coins for counterfeits, missing good opportunities.

Fortunately, genuine coins have several distinctive features. By paying attention to these, you can easily tell real from fake, even as a novice. I will now analyze the key features of authentic Great Wall 1 Yuan coins from five aspects: front design, back design, shape and size, material and texture, and craftsmanship details.

(a) Front Design: The Great Wall, Grand and Well-Defined

The front of the coin is the most important identification point. Genuine coins feature a clear, detailed image of the Great Wall, with smooth, well-defined lines and consistent craftsmanship. Counterfeits often have blurry images, crooked characters, or missing details.

The authentic front depicts the winding Great Wall with watchtowers, symbolizing resilience and long history. The main features to check:

• Great Wall image: The lines are smooth, with distinct layers and no blurring. The wall extends from the lower left to upper right, with visible watchtowers. The mountain background is simple but natural, with no extraneous decorations.

• Year digits: Located at the bottom, the year (1979–1986) is in a standard, neat font—宋体 (Song typeface)—with consistent size and spacing. The digits are centered, not crooked or distorted.

• Edge serrations: The serrated edges are uniform, with no irregularities or missing teeth.

Tips: Use a magnifier to examine the wall pattern: genuine coins show clear, textured bricks; fakes may have fuzzy or uneven lines. Also, compare the year digits with official images to spot inconsistencies.

(b) Back Design: The National Emblem, Respectful and Symmetrical

The back features the Chinese national emblem—Tiananmen Gate with five stars—symmetrically arranged, with “People’s Republic of China” and “Yuan” denomination.

Key points:

• National emblem: The Tiananmen Gate is detailed, with clear outlines of the gate, stars, and surrounding elements. The design is symmetrical and proportionate.

• Text: The characters “中华人民共和国” (People’s Republic of China) and “壹圆” (Yuan) are in a standard font, evenly spaced, with no smudges or distortions.

• Overall layout: The emblem and text are centered, with balanced spacing, and no extraneous marks or irregularities.

Tips: Use a magnifier to verify the clarity of the emblem’s details. Fake coins often have fuzzy or incomplete emblems, misshapen characters, or uneven layout.

© Shape and Size: Precise Dimensions and Weight

Authentic coins have strict standards:

• Diameter: 30 mm (±0.1 mm). Use a caliper for measurement; genuine coins are very consistent.

• Thickness: About 1.9 mm (±0.1 mm). Feel the weight; genuine coins are solid and weight around 9.32 grams.

• Weight: 9.32 grams (±0.1 g). Use a precise scale; lighter or heavier coins are suspect.

Tips: Slight deviations are normal due to wear, but large differences suggest a fake. For example, a coin weighing less than 8.8 g or over 9.8 g is likely counterfeit.

(d) Material and Texture: The Copper-Nickel Alloy

Authentic coins are made of copper-nickel alloy (“white copper”) with specific characteristics:

• Color: Natural silver-gray with a warm luster, not overly shiny or dull.

• Feel: Heavy and cool to touch, with a solid, dense feel. It conducts heat quickly, warming up in your hand.

• Surface: No obvious casting flaws, bubbles, or rough spots. The surface is smooth, with fine details.

Tips: Scratch lightly with a fingernail; genuine coins resist scratches, while fakes may show marks or be softer.

(e) Craftsmanship Details: Fine and Consistent

Authentic coins exhibit high-quality craftsmanship:

• Edge serrations: Uniform, smooth, with no irregularities or roughness.

• Surface finish: No casting flaws, no flow lines, no bubbles, and no rough patches.

• Pattern details: Sharp, well-defined, with no blurring or smudging.

• Overall symmetry: The design is balanced, with no distortions or asymmetries.

Tips: Examine the coin under good light and magnification. Any rough edges, uneven patterns, or obvious flaws indicate a fake.

Summary: How to Avoid Fakes and Pitfalls

• Check the edge serrations: They should be uniform and smooth.

• Measure dimensions and weight: Use precise tools; deviations suggest counterfeits.

• Inspect the front and back details: Clear, sharp images and characters are signs of authenticity.

• Feel the material: Heavy, cool, and dense—consistent with copper-nickel alloy.

• Examine the surface finish: No casting flaws, bubbles, or rough patches.

• Beware of artificially engraved patterns: Some fakes have fake brick patterns or other details added manually, which feel rough and uneven.

By mastering these key features, even beginners can confidently identify genuine 1980 Great Wall 1 Yuan coins and avoid falling for counterfeit or low-quality fakes, ensuring your collection’s authenticity and value.
