I assume we are only talking about CCGTCC Club member personals.
I have way too many to search for that info. Have no info in my program on dates the early ones were made.
Give me a name and I will tell if I have it. I have some that go back before the club formed.
The most expensive is most likely Bill Borlands. I have seen them go for as much as $50 on ebay. I have 6 different of his, circa 1990 or so.
