has any one seen the state quarters with an "S" mint stamp on them before? I have 3 quarters with it.

Question

I have 3 different states with a "S" stamp on it. for the mint.

Answer 1

Hi. I'm a coin dealer in the Midwest. The "S" mintmark means that they were struck in San Francisco. The quarters you have were broken out of a Proof Set, which is a special multiply-struck set made specially for collectors. If you look at the coins, you'll notice that they have a shiny, mirrorlike background with frosted details. These are the characteristics of a Proof coin. These were made for proof sets only and were never intended to be circulated. What this means is someone broke up a proof set (stupidly)and spent it as change.

Your S-mint quarters are worth much more than a quarter...they will average out at a minimum of $2-3 each or more, depending on which states you have, and whether the surfaces were scratched or damaged from their brief exposure to circulation. They also might be silver...look at the edge...if you don't see a streak of copper, then they are silver and worth more. I'd recommend keeping them in a holder of some type to keep them from getting any fingerprints or scratches. And DON'T try to clean or polish them; it will ruin their value.

Hope this info helped you out.

Answer 2

S means it came from the San Francisco mint.

On older money, as S is slightly more rare than other mints, and may be worth a little more.
On newer money, the S is only used on proofs for sale to collectors, and not circulated.

Answer 3

they may be from an uncirculated or proof set made for coin collectors

Answer 4

That's not right

Answer 5

I think it depends
