Dansco 7100 Or 8100

I have the 8100. It's set up so that the book doesn't have holes for all the Proofs until there were "Proof only" years, i.e. from 1975-S & onward.

So even though there were Proof issues for earlier years, for 29 years between 1936-1974 (not every year were there Proof issues), the "Proof only" years started with the 1975-S. Proofs were issued from 1936-1942 (Philly mint), from 1950-1964(Philly mint), & from 1968-S to 1974-S (S.F. mint).

For those 29 years, there were also simultaneous issues of non-Proofs (e.g., 1936, 1936 Proof; 1964, 1964 Proof; 1968-S, 1968-S Proof).

There were 35 "Proof only" issues for all the years from 1975-S to 2009-S, i.e., all the S mints from 1975 to the present are Proofs. I hope this is not too confusing.

BTW, the 8100 that I have only goes until 2007. I have to buy an additional page for the dates after 2007.

I was able to buy a Proof set from 1975 to the present on ebay.

I went with the 8100, I remember when they went to a proof only in 1975. In fact I bought the 1975-S and still have it (in my 8100). I also ripped open a bunch of duplicate proof sets and while you are doing that, you might as well save the proof Jeffersons, etc. See where this is going?

Robert, no. There are no rarities to speak of that would come anywhere near being called a "key" or "semi-key."
