Where are the PR70 Washingtons 1960-1964 ??

MoneyLA

there aren't many, and if you don't mind, PM me with what you have or post them here. I'd like to know if these are "concentrated" in a few collections or dispersed among many.

for the record, I have the following:

1960 1
1961 1
1962 1
1963 1
1964 1 but a second one was recently purchased and Im awaiting delivery
