Has anything ever been documented as to why the Mint did not strike 40% SMS 10c & 25c?
The SMS coins of 1965, 1966, and 1967 each contain 40% silver Kennedy halves. This we know. I wonder why, though, as these were limited and specially struck coins for collectors, why the dime and quarter were also not minted on 40% silver planchets? I'd be curious to read any articles as to why yet have not located anything so far.
Any speculation on your part?
