How much is a 2002 Louisiana silver quarter with an S mint stamped on it worth?
Assuming your silver proof quarter does not have any visible nicks or scratches, it is worth $3-$4 -- otherwise it's worth about $1 (Deleted my previous update. Since the S mint mark only appears on proof coins this could not be a circulation strike. The first answer above is correct as it stands.)
Copper-nickel, not silver, just like all the other quarters out there in change. Unless it's uncirculated, it's only worth a quarter. A P mint mark, not a "P Mint" - that would be the entire Philadelphia Mint building! The only silver state quarters were issued by the San Francisco mint ("S") and were sold in special "prestige" coin sets. All coins from Philadelphia were made out of copper-nickel.
We have a 1906 quarter MINT condition sealed in air tight coin frame.What is a 1906 quarter stamped with capital A on the head side neck area and the reverse side on the middle of eagles chest worth?
You don't have a pure silver quarter as the US has never minted a pure silver (99.9% pure or higher) silver quarter. Instead what you have is a 90% silver quarter which would be dated 1964 or prior. The value depends on a number of factors including the date, the mintmark and the condition. But a silver quarter is worth $5-6 in scrap silver regardless of type or condition, however some quarters can be worth…
