I think I did too. I have several cent books 1944-1980 or something like that and the slots were filled, but the coins don't look right. I am just going to buy a small date so I have one to compare to. Spending way too much time for so little result. LOL Actually, it's the eyestrain.
No luck with my 70-S rolls either, although now I have one more thing to look for in my roll searching!
I took the roll that I scanned at 2400 dpi and blew it up to 1000x on the HD monitor. I may have a couple. The 9's are different for sure, but without a comparison coin, I feel it is an impossible task. LOL
Try reading this thread. The small/large date is discussed in detail - great detail. There are pictures. references, id's, how and why they exist, etc. and so on. http://www.cointalk.com/t93080/
