Coins are an essential component of everyday transactions, with millions of them changing hands each day. While the majority of these coins are merely worth their face value, few have garnered great value due to distinctive characteristics, minting faults, or restricted manufacturing runs. Coins from the 1970s are especially noteworthy, as several have become quite expensive due to their scarcity and unique features.
Collectors and numismatists frequently seek out these uncommon coins, expecting to find hidden jewels within seemingly ordinary pocket change. Certain 1970s coins, due to minting faults or odd production variances, have sold for more than $10,000 at auctions and private transactions. These coins’ value is determined by rarity, condition, and collector demand.
5 Coins That Are Worth More Than $10,000
1971-S Lincoln Cent with Double Die Obverse
The 1971-S Lincoln Cent with Double Die Obverse is the first coin to appear on this list. Minting faults, such as duplicate die strikes, occur when the die imprints the coin more than once. Lincoln’s visage and writing are doubled on this coin, giving it a distinctive appearance that appeals to collectors.
The double minting of this piece produces a noticeable doubling appearance, particularly on the inscriptions and Lincoln’s profile. Coins in good condition can fetch up to $10,350, making it one of the most valuable findings from the 1970s. This type of error is uncommon, as quality control at mints typically detects such inaccuracies. However, when they do make it through, their scarcity drives up auction prices significantly.
1974-S Lincoln Cent with Brockage Error
Another unusual 1970s coin is the 1974-S Lincoln Cent with a 1973-S Brockage Error. Brockage mistakes occur when one side of a coin shows a normal picture while the other side shows a mirror image caused by a minting fault.
In this example, the 1974-S Lincoln Cent has an unusual feature: the reverse side contains a blockage of the 1973 design, resulting in a reversed and misplaced image of Lincoln’s bust. Coins with blocking defects are rare and so in high demand. This piece, in mint condition, could possibly be worth more than $10,000.
1979 Susan B. Anthony Dollar Struck Over a 1978 Jefferson Nickel
The 1979 Susan B. Anthony Dollar is an iconic piece, but when its design is transferred to a different coin due to a minting error, it becomes unique. In this example, the Susan B. Anthony Dollar was struck on a 1978 Jefferson Nickel. The end result is a one-of-a-kind blend of features from both coins, a clear example of a manufacturing error.
Collectors are interested in such blunders because they provide insight into the complicated world of minting procedures. This coin is the perfect example of an overstrike error, which occurs when an existing coin is erroneously restruck with a new design. Because of its rarity, a specimen of this coin has been known to fetch more than $15,000 at auctions.
1971-S Deep Cameo Proof Penny
The 1971-S Deep Cameo Proof Penny is another desirable coin from the 1970s, distinguished by its distinctive proof polish. Proof coins are made to be used as models or collectibles rather than for regular circulation. They are struck with specially designed dies, which produce highly polished surfaces and frosted features that provide a cameo look. The deep cameo version enhances this effect by creating a stark contrast between Lincoln’s bust’s glossy fields and matte parts.
Proof coins like this are extremely valuable due to their precise creation process and scarcity. A Deep Cameo Proof Penny from 1971 sold at auction for more than $17,000, demonstrating its value to collectors. This coin was never intended for general circulation, which explains its perfect condition and worth.
1970-S Lincoln Cent with Small Date Variation
The 1970 Lincoln Cent with a Small Date is another noteworthy uncommon coin. Unlike the standard 1970-S cent, this variant features a smaller and more subtly crafted date, as well as special numerical properties that expert collectors will recognize right away.
The variation in date size may appear insignificant, yet it adds great value due to its scarcity. Collectors are always on the lookout for such minor features, which can suggest a unique variety or a limited mintage. A 1970s Small Date Lincoln Cent in exceptional condition can fetch $18,000 or more at auction, depending on its condition and demand.
Coin Value Factors
A coin’s worth is determined by a variety of factors, including:
- Rarity: Coins that were made in small quantities or include uncommon flaws are frequently rare, which increases their market value.
- Condition: Coins that have been well-preserved and show little indications of wear are more valuable. Coins classed “uncirculated” or “proof” attract greater values.
- Demand: Collector demand for specific coins, particularly those of historical significance or with unusual qualities, has a substantial impact on their value.
- Errors and variations: Coins with minting faults, such as double strikes, overstrikes, or distinctive design variations, are typically worth significantly more than ordinary coins.
