I found this 1999 P Georgia quarter that appears to be on a silver planchet It appears to be a little thicker then a normal quarter. What have I got? Experimental planchette? Yes
Wellcome to CT do you know if it is magnetic and how much does it weigh? I looks promising. Do you have a coin dealer that you trust to check it out because if it's what you think it is you will have to send to a third party coin certification service ex: PGS, ANA, PCGS. I wish you good blessings and mucho $$$$$$$$!
@TONYBRONX Thank you Tony.....It is NOT magnetic. I don't have a scale that does partial grams. Will take it to a jeweler friend tomorrow and have him weigh it for me.
There were silver state quarters minted for proof sets. It is conceivable that a proof set was opened and put into circulation. If so, the silver quarter would have a very distinct ring to it. More likely it was plated as @masterswimmer said. Lots of these state quarters were plated by third party marketers.
With the introduction of the State Quarter program in 1999, third-party resellers sent bulk submissions to the grading services with the expectation of receiving some high grade specimens that they could flip for huge profits. Those coins that didn't make the minimum grade were simply returned to the resellers "as is". Some of those resellers got the bright idea of creating sets with these coins plated in very, very, very thin layers of precious metals like gold, silver & platinum. So, instead of being stuck with a pile of coins worth just face value, they now had a new way of sucking more money from the uneducated public. Years later, many of these "suckers" discovered that these sets were not worth the money that they paid for them, so they dumped them back into the market place at face value. Chris
