Rare 1975 'No S' Dime Expected to Fetch Over $500,000 at Auction

Three Ohio sisters inherited a rare 1975 dime missing the 'S' mint mark, housed in a bank vault for over four decades. The coin, expected to fetch over $500,000, is one of only two known to exist. The sisters' brother initially purchased it in 1978 as a financial safety net.

Three sisters from Ohio who inherited a rare 1975 dime, missing the 'S' mint mark, have held onto the valuable coin for more than 40 years without realizing its true worth.

Ian Russell, president of GreatCollections, a currency auction specialist, revealed the coin could garner over $500,000 in an online auction slated for October.

The dime, one of only two without the mint mark, remained hidden until its recent discovery, with the other one selling for $456,000 in 2019. It will be displayed at a Tampa coin show before the auction's conclusion, likely inspiring renewed interest in similar proof sets.
