Another Penny Box and Proof Question

[MentalUnrest]

My son did another box of pennies today, and had some alright results. He occasionally does penny boxes, not his best, but still pretty good. Here are the results:

US: Canada:
1930 (1) 1981 (2)
1941s (1)
1946d (1)
1949 (2)
1951s (1)
1952d (1)
1956d (1)
1957d (2)

He found two good pennies that are not wheats, but still cool.
1959 BU (1)
1969 Proof? (1)

Any way to tell on if a penny is a proof? The Halves, Quarters and dimes are easy as they have the S mint mark, but never knew how to tell a penny proof.


Thanks and HH

Your '69 isn't a proof. The Mint in San Francisco started making the proofs in 1968 I believe. So all proofs from 1968 on, regardless of denomination, will have the "S" mintmark. However, the SF mint also produced "business strike" coins for general circulation until 1974. So, there are "S" mintmark pennies (and nickels) from 1968-1974 that are not proofs.

Proofs from 1967 and before were struck in Philadelphia and therefore have no mintmark.

99% sure this info is accurate. If its not, I'm sure someone will chime in.

1964 was last year proofs were in Philadelpia.
1965 - 1967 were SMS coins (also Philadelphia)..
1968 and later, proofs were all minted in San Francisco

Halves, quarters, and dimes are not any easier as the proofs in those denominations were also minted at Philadelphia 1964 and earlier.. I haven't found any silver proofs, but do have a 1964 nickel that is really beat up and possibly a proof..

The '69 was whizzed. Somebody took a Dremel or something with a buffing wheel and polished it up. You can tell because of the dull areas near the devices. A proof would be uniformly shiny in the fields.
