I do love those pieces. I have a couple of well work ones that my father gave me from his time in Vietnam, and every now and then I find a nice one, but nothing likel your collection man.
a great deal even though the fractional Series 661 is very common thru $5, the $10 and $20 from this series are much rarer this was the first series that had $20 in it i personally have the $10 in PCGS 67PPQ pop 1 of one and the $20 i PCGS 68PPQ also one of one both are the finest examples known each note is valued over $10,000 !! the $20 is featured on my avatar
Very nice notes! I've been collecting MPC's for about 10 years, but don't have any that are graded... If you have any raw examples that are for sale, please send me a PM... Thanks Doug
