Understanding Mintmarks and Their Significance
Mintmarks are small letters on coins indicating their minting location. In 1968, the United States Mint resumed the use of mintmarks after a hiatus from 1965 to 1967, during which mintmarks were omitted to discourage coin hoarding amid a coin shortage.
The San Francisco Mint’s proof coins were designated with an “S” mintmark. However, due to a minting error, some 1968-proof dimes were released without this mark, leading to the creation of the rare 1968 No S Dime.
The Rarity and Value of the 1968 No S Dime
The scarcity of the 1968 No S Dime significantly contributes to its high value. Estimates suggest that only about two dozen of these error coins exist today. Their rarity has driven auction prices to impressive heights, with some specimens selling for up to $40,800. The value of these coins can vary based on their condition and the demand among collectors.
Identifying a 1968 No S Dime
To determine if you possess a 1968 No S Dime, consider the following characteristics:
- Proof Finish: These dimes exhibit a mirror-like finish, a result of being struck multiple times on specially prepared planchets.
- Absence of “S” Mintmark: Unlike standard 1968 proof dimes from the San Francisco Mint, these coins lack the “S” mintmark.
- Sharp Details: The design elements are crisply defined, a hallmark of proof coins.
It’s important to note that regular 1968 dimes minted in Philadelphia also lack a mintmark but are not proof coins and do not share the same value.
Historical Auction Prices of the 1968 No S Dime
The 1968 No S Dime has achieved notable prices at auctions over the years. In 1997, a Proof-68 example sold for approximately $6,000. By 2005, a similar grade specimen commanded $32,200. As more examples have been discovered, the value has adjusted slightly, with current estimates ranging between $15,000 and $25,000, depending on the coin’s condition and market demand.
