Would you take a half a million dollars in exchange for a common dime?
That's the value of a proof copy of the 1975 "No S" Roosevelt dime. Only two of these coins are known to exist, and one of them sold at auction for $456,000 in 2019.
Don't bother to look for another in the nearest coin jar, because you won't find it in there. The "No S" dime — meaning that the first 'S' in San Francisco Mint is missing from the dime — is a proof copy, a fancy coin with high detail that is encased in plastic. It is not meant for circulation.
Of course, the half-million dollar dime isn't the only 1975 "No S" Roosevelt dime, but the flawless proof copy is by far the more valuable of the two.
