No mintmark always equals Philadelphia?

I know that on circulating coinage, the absence of a mintmark indicates that a coin was minted in Philadelphia. Is the same always true on non-circulating coinage, such as American Gold Eagles and the 1926 Sesquicentennial commemorative coin?

    Generally, yes. One exception that I can think of is the 1922 cent where the D mintmark was removed by over polishing the die.

    Lots of circulating coins with no mintmarks were minted elsewhere. West Point minted cents in the 1970's. Then there's the obvious 1965-1967 coinage etc. SMS sets were minted in SF also.

    A portion of 1840 half dollars without a mintmark were minted in New Orleans.

    They've done a lot of eagles at West Point with no mint mark

    The Pilgrim commem has what appears to be a “D” mint mark but was actually
    Minted in Philly. In this case, the “D” stands for Cyrus Dallin, the coin’s designer.

    Certain years for ASE’s had no mint mark but were minted in San Francisco.

    Interesting. So I guess "no mintmark" means, at best, that a coin likely was minted in Philadelphia. Thanks.

    I think that statement gives the wrong impression.

    With a few exceptions, such as those mentioned above, lack of a mintmark is a definite indicator that a coin was minted in Philadelphia - not "likely minted", but definitely minted. The exceptions are known and only in those specifics cases is there an alternate scenario.

    Don't forget the Mysterious 40% Silver Bicentennial Proofs (Type One Quarter and Half, Types One and Two Dollars) struck without an S mint mark, where the lack of a mint mark may indeed mean a Philadelphia strike!
