What Proof Coins Are Required To Make Your Series Complete?

It's been about 34 months since I last posted on this topic and decided to post my updated checklists.

Lincoln Cents: Need 1936,'37,'38,'39,& 1940.
Jefferson nickels: Complete
Roosevelt dimes: Complete
Washington quarters: Complete (yes, finally got that 1936)
Franklin halves: Need 1950, 1951, & 1952.
Kennedy halves: Complete
Eisenhower dollars: Complete
S.B.Anthony Dollars: Complete
Presidential dollars: Complete
Saq/Native American Dollars: Complete
Innovation Dollars: Complete.

PS: My sets do NOT include any 'pre-set' (before 1936) proofs or minor variations.

I began collecting business strikes many years ago, filling the holes with Lincolns and Jeffersons. I recall my father bringing home a Christmas saver's book for dimes from the credit union. Sadly, I can not seem to locate that one. But, this was how coin collecting began for me. And probably like most of you.

My first proof coin came in the form of set, the 1994 Olympic as a gift. Soon after I bought a regular release set, then another and so on. All of which are still as they were packaged and shipped. Which I now have back to 1955 (including the SMS sets if we're counting those).

Answering a great question, by the way, I for one do not consider them necessary for a complete series. Only for the above reason, beginning with business strikes meant for commerce. So for myself it's a separate collection entirely as I am trying to complete them. At some point I'd like to go back before 1936 when the coins were issued individually as well. Those can get pricey. Especially if I would be extremely fortunate enough in finding some with their original packaging/envelopes. They are out there.
