Valued coins can be found a few decades back in the disco and leisure suit era. The most valuable 1970s U.S. coins can sell for five figures.
Like many collectible coins, the most valuable 1970s coins have a unique flaw or defect. They have pennies and nickels, the lowest denominations.
1971-S Doubled Die Obverse Penny: $10,350 Die (or design stamp) strikes the metal numerous times on the front (obverse), reverse, or both sides, causing double die faults.
Reverse Brockage of 1973-S Penny: $11,400 A high-grade Lincoln cent sold for $11,400 at Heritage Auctions in 2020. Collectors like “Brockage” coins because they feature the standard design on one side and the mirror image on the other.

1971-S Deep Cameo Proof Penny: $17,250 A “proof” coin is a blueprint for future coins, not currency. Proof coins are “the most beautiful and perfectly minted coins possible,” according to LoveToKnow, calling this Lincoln cent a “superb proof.”
1970-S Small Date Penny: $18,400 Dave's Collectible Coins blog describes this unusual 1970-S small-date penny as having “a more delicate date of a finer punch as compared to the large date variety.” Large-date coins have a 7 that is “relatively level” with the rest of the date, but small-date coins are not.
