In my Dansco 8100 there is only one space for an S-mint marked cent from 1968-1974. I currently had the business strike S coins in there- but just bought a lot of proofs to fill from 68 to present. Is there is not a page that includes a space for both the business AND proof?
Most can tell the difference between the two, and most just use the albums to collect from loose change, or finding cheap ones on auctions.
The Dansco 8140 for Washington Quarter is the same way in that there are a handfull of proof holes that are not in the original album. I purchased a blank quarter page and added to the back of the album to put these and some other major varieties. I was never able to get a straightforward answer why it was this way.
The 8100 is just for business strikes. Dansco makes another one that includes the proofs for 1968 and up but I don't remember the number.
"Lincoln Cents 1909-2009 w/Proofs Dansco Album #8100" You are thinking of the Dansco #7100 for circulation only.
I put a blank page in the back of the album for the proofs. They looked really nice for many years. Now they have dark spots from the cardboard dust and haze cover most of them. Wish I had put them in a better type holder.
