That's right, those three coins are on my wish/target list (I feel the Strike and Luster on these three are outstanding). After much searching at coin shows last year (including the ANA) I just got an 81S in a MS65 PCGS holder. This was at a LCS not a show. I had to pay brick and mortar prices but this was the best coin I could find in the type and grade. So after more thought I want all three in 66! The coin show circuit near me starts in two weeks. If my luck is like last year I am not holding my breath. These are common coins in high grades and I don't know how easy they are to find. Any suggestions?
