How do you know it was a proof? Just by the " S " mint? Is this for all pennies or certain years? And is the S mint proof just for pennies or all coins? Thanks guys.
... There are many mint sets that carry the S mark that are not proofs...

There are? I am unaware of these.
There are? I am unaware of these.
They don't exist. There are some "S" minted ATBs that are not proof, but these were not in mint sets I think.
You get a pass this once just because you weren't born, yet. Not being hard on you, but you know better.
Any business strike cents produced in San Fran will be issued in the respective mint set. '68, '69, '70, '71, '72, '73, and '74 mint sets include a P/D/S mint cent.
I only mentioned cents as it pertains to the OP thread. But look at the mintage of Nickels. In '68, '69, and '70, there was no nickel production in Philly. Mint sets have a D/S mint nickel.
I knew about these of course. MU stated that there were business strike "s" mintmarked cents, nickels, dimes, and quarters up to certain years...and then went on to say that there are other "s" mintmarked coins that are not proofs as well. Outside of the business strike 40% silver bicentennial half, I am unaware of any others.
