Have you ever wondered if those dusty old coins sitting in your drawer might be worth more than their face value? Well, it’s time to start digging through your coin jars and checking your pocket change, because some coins from the 1970s could be worth thousands of dollars! The disco era wasn’t just about bell-bottoms and platform shoes – it also produced some of the most valuable modern coins in American numismatics.
What makes these 1970s coins so special? In many cases, it’s minting errors, unique variations, or limited production runs that transform ordinary pocket change into extraordinary treasures. Like finding a diamond in a coal mine, discovering one of these rare coins could be your ticket to an unexpected windfall.
In this article, I’ll walk you through five incredibly valuable coins from the 1970s that could be worth up to $15,000 or more. I’ll explain what makes each coin special, how to identify them, and what they might be worth in today’s market. So grab your magnifying glass and let’s start hunting for treasure!
What Makes 1970s Coins So Valuable?
Before we dive into specific coins, let’s understand why some 1970s coins command such impressive prices. Unlike ancient coins whose value often comes from their age and historical significance, 1970s coins derive their value from different factors:
- Minting Errors: The most valuable 1970s coins typically feature some kind of production mistake. These errors include doubled dies (where design elements appear doubled), off-center strikes, or wrong planchets (the metal discs used to make coins).
- Limited Mintage: Some coins were produced in relatively small numbers, making them naturally scarce.
- Condition: Coins in pristine, uncirculated condition (often graded MS-65 or higher) can be worth significantly more than the same coin showing wear.
- Variations: Some years produced coins with subtle design variations, like the small date versus large date pennies of 1970.
Think of these factors as ingredients in a recipe for numismatic value – the more of these elements present in a single coin, the more valuable it becomes. Now, let’s explore the five most valuable coins from the 1970s that could be hiding in your collection.
Top 5 Most Valuable 1970s Coins
1. 1970-S Large Date Doubled Die Obverse Lincoln Penny
The crown jewel of 1970s coins is undoubtedly the 1970-S Large Date Doubled Die Obverse Lincoln Penny. This coin features a prominent doubling error on the obverse (front) side, particularly visible in the word “LIBERTY” and the date.
What makes this penny so special is the combination of three factors: it’s a proof coin (specially struck for collectors), it has the large date variety, and it features a dramatic doubled die error. This trifecta of numismatic desirability has pushed its value to extraordinary heights.
In 2001, one of these pennies sold for an astonishing $24,150! Even accounting for inflation, that’s a remarkable return on a one-cent investment. It’s like finding out that old baseball card in your attic is actually a rare Babe Ruth rookie card – a humble item transformed into a valuable collectible.
How to identify it: Look for a 1970 penny with an “S” mint mark (indicating it was minted in San Francisco). Check if the “7” in the date appears level with the other numbers (indicating the large date variety). Then, using a magnifying glass, look for doubling in the lettering of “LIBERTY” and in the date.
2. 1970-S Small Date Lincoln Penny
Coming in at number two is the 1970-S Small Date Lincoln Penny. While not as valuable as its large date counterpart, this coin can still fetch up to $18,400 in pristine condition.
The difference between the small date and large date varieties is subtle but significant. In the small date version, the “7” in 1970 appears higher and smaller compared to the other digits. This minor variation makes a major difference in value.
How to identify it: Look for a 1970 penny with an “S” mint mark. Examine the date closely – if the “7” appears higher and smaller than the other numbers, you might have the valuable small date variety. For accurate identification, compare your coin with reference images or consult a professional numismatist.
3. 1971-S Deep Cameo Proof Lincoln Penny
The 1971-S Deep Cameo Proof Lincoln Penny is another high-value coin from the 1970s, with specimens selling for up to $17,250. “Deep Cameo” refers to the striking contrast between the frosted design elements and mirror-like fields (background) of the coin.
Proof coins are specially struck for collectors using polished dies and planchets, resulting in coins with exceptional detail and finish. Deep Cameo proofs represent the highest quality of these already premium coins.
How to identify it: Look for a 1971 penny with an “S” mint mark that has a mirror-like background and frosted, almost three-dimensional design elements. This contrast should be dramatic and immediately noticeable. Remember that proof coins were not intended for circulation, so finding one in your pocket change is unlikely – but not impossible if someone broke open a proof set!
4. 1974-S Reverse Brockage of 1973-S Lincoln Penny
One of the most fascinating error coins from the 1970s is the 1974-S Reverse Brockage of 1973-S Lincoln Penny, which sold for $11,400 at auction. A “brockage” is a rare minting error where one side of the coin shows the normal design, while the other side displays a mirror image of the opposite side.
In this case, the coin shows the standard 1974-S Lincoln penny obverse, but the reverse features a backwards impression of a 1973-S Lincoln penny obverse. It’s like a photographic negative pressed into metal – a truly unique error that fascinates collectors.
How to identify it: This is an extremely rare error coin. The obverse will look normal, but the reverse will show a backwards, incuse (sunken) image of Lincoln instead of the Memorial building. Due to its rarity, authentication by a professional grading service is strongly recommended.
5. 1971-S Doubled Die Obverse Lincoln Penny
Rounding out our top five is the 1971-S Doubled Die Obverse Lincoln Penny, which has sold for up to $10,350. Like the 1970-S doubled die, this coin features doubling in the obverse design, particularly noticeable in the lettering and date.
While not as dramatic as the 1970-S version, the 1971-S doubled die is still a highly sought-after error coin that commands impressive prices, especially in mint or near-mint condition.
How to identify it: Look for a 1971 penny with an “S” mint mark. Using a magnifying glass, examine the lettering (especially “LIBERTY” and “IN GOD WE TRUST”) and the date for signs of doubling. The doubling effect creates a shadow-like appearance, as if the text was stamped twice slightly offset from each other.

How to Authenticate Valuable Coins
If you think you’ve found one of these valuable coins, it’s important to authenticate it properly. Here are some steps to follow:
- Visual Inspection: Use a magnifying glass to examine the coin’s details, looking for the specific characteristics described above.
- Weight and Measurements: Check that the coin’s weight, diameter, and thickness match the official specifications for that type of coin.
- Magnet Test: Genuine copper pennies won’t stick to a magnet. If your penny is attracted to a magnet, it might be counterfeit or altered.
- Professional Grading: For coins that appear valuable, consider having them authenticated and graded by a professional service like PCGS (Professional Coin Grading Service) or NGC (Numismatic Guaranty Corporation).
Remember, authenticating valuable coins is like detective work – you’re looking for specific clues that confirm your coin’s identity and value. Don’t rush to conclusions or clean your coins (which can significantly reduce their value).

FAQs About Valuable 1970s Coins
1. Should I clean my old coins before trying to sell them? No! Never clean your coins. Cleaning can significantly reduce a coin’s value, as collectors prefer coins with their original surfaces intact. What might look like dirt to you could actually be valuable toning or patina that authenticates the coin’s age.
2. How can I tell the difference between the 1970-S small date and large date pennies? The main difference is in the appearance of the “7” in the date. On the small date variety, the “7” sits higher than the other digits and appears smaller and more delicate. On the large date variety, the “7” is more level with the other numbers and appears bolder.
3. Are there any other valuable coins from the 1970s worth looking for? Yes! While we’ve covered the five most valuable coins, others like the 1979 Susan B. Anthony Dollar overstruck on a 1978 Jefferson Nickel (worth around $15,000) and various other error coins from this decade can also be quite valuable.
4. Where’s the best place to sell valuable coins if I find them? For highly valuable coins, reputable auction houses that specialize in numismatics often get the best prices. For coins worth less than $1,000, you might consider coin dealers, online marketplaces for collectors, or coin shows. Always get multiple appraisals before selling.
5. What tools do I need to start hunting for valuable coins? At minimum, you’ll need a good magnifying glass (at least 5x magnification), a digital scale that measures in grams, and reference materials showing what to look for. A digital caliper for measuring diameter and thickness can also be helpful for authentication.
