I used to collect the round,shiney metal discs and have switched over to US Paper Currency. I am fairly new to CoinTalk and was wondering where members go to ask for trades, values, or find someone that may want to purchase these sets. I can photograph the sets, but it's a fairly simple and common commodity. 1999-2010 United States Mint SILVER Proof sets including the quarters. Please PM me with advise.......Thanx
