I collect Washington quarters in NGC and have gotten to the point where I have to buy PCGS and try to cross-over. When I cannot find a PCGS green been I have to try buying and hoping. Sometimes I must buy several PCGS quarters and try to get an NGC at great expense. I bid on Heritage but I caught them bidding against me and found the coin in their inventory later on. Same serial number. I buy in a lot of unsearched mint sets that have been searched. I am a point where I am looking at a lot of ugly brown toned quarters that have high populations but I am unwilling to settle.
