@Phil Ham Are you still willing to share your spreadsheet? I've sort of done a similar spreadsheet so I am interested to compare.
Phil...thanks for sharing your spreadsheet. I agree with everything you've included/excluded except for your inclusion of the three 1981 (P,D,S) Susan B. Anthony dollars. My understanding is that they were for collectors only (not intended for circulation). I will double check my understanding and get back to you. FWIW, I need 172 coins to complete this set (regardless of the disagreement I mentioned above). Again, thanks for sharing!!! My main focus of my collection is coins that have circulated so this is very fun to share!!!
Thanks, I've removed them from my list. As I had them all, I'm still at 11 remaining coins to complete my 20th century circulation set.
My daughters gave me a 1913-S Type 2 Buffalo nickel for Christmas. It was graded by ANACS at VF-25. I also got a digital microscope from my stepsons. I'm now down to just 10 coins to complete my 20th century US circulation set. I've now completed the 20th century nickel collection.
[QUOTE="(3) I exclude error coins, date varieties, mint mark varieties. etc. Some key examples includes the three legged Buffalo, 1955 DDO cent, 1960 and 1982 small and large date cents, 1945 Mercury dime micro S, and many date overstrikes. [/QUOTE] Does that mean you have not counted ANY 1960 or 1982 Lincoln Cents?
