i found a 1999 p Delaware Quarter that has no copper showing from the side, it weighs 5.7, i look too see if any were made, all i can find are the S silver proofs....
Hmm ok Silver plated for what? uncirculated? i find nothing about Plated for that year..just the copper and silver proofs..
If it is plated it would have been plated outside the Mint. The infomercial TV shows that sell garbage (colorized coins, gold plated coins, etc.) to people that don't know any better could have plated the quarter.
