Today, there are only nine 1894-S proof Barber dimes known to exist, and each one sells for over $1 million. One similar cent sold for $1.9 million in 2016, according to Bankurapolice.
It goes without saying that a dime’s value increases with its age. Therefore, keep an eye out for any from the early 20th or 19th centuries.
Keep a look out for any Roosevelt dimes made before 1965, according to Gainesville Coins, since they are worth far more than their face value due to their 90% silver content.
Modern dimes lacking the S mark are worth looking for since currency with errors may also be quite valuable.
