when was the last year silver dimes were made?
1965
with the coinage act of 1965, the mint transitioned to striking clad coins, made from a sandwich of copper nickel around a core of pure copper. there are no mint marks on coins dated from 1965 to 1967, as the mint made efforts to discourage the hoarding that it blamed for the coin shortages that had preceded the 1965 act. the mint modified the master hub only slightly when it began clad coinage, but starting in 1981, made minor changes that lowered the coin's relief considerably, leading to a flatter look to roosevelt's profile. this was done so that coinage dies would last longer. mint marks resumed in 1968 at denver and for proof coins at san francisco. although the california facility beginning in 1965 occasionally struck dimes for commerce, those bore no mint marks and are indistinguishable from ones minted at philadelphia. the only dimes to bear the "s" mint mark for san francisco since 1968 have been proof coins, resuming a series coined from 1946 to 1964 without mint mark at philadelphia. starting in 1992, silver dimes with the pre-1965 composition were struck at san francisco for inclusion in annual proof sets featuring silver coins. beginning in 2019, these silver dimes are to be struck in .999 silver, rather than .900, which the mint no longer uses.
