Wow that's quite the set of Sheldons. Would you happen to have a photo library that I could use as a variety resource. I have a bunch of books, but reading the description and matching it can be pretty difficult for some dates.
No, and even if I did my collection would not make a good photo reference. I've mentioned this several times. If you want a good one use the Dan Holmes collection. EVERY variety including ALL the NC's, higher grades, and good images. http://images.goldbergauctions.com/php/toc_auc.php?site=1&lang=1&sale=54 For my own use I've downloaded the images from the catalog. Eventually I'm going to combine them with the descriptions from the Robbie Brown catalog. (It was a great catalog for its time. All the S numbers and most of the NC's Every variety pictured and with descriptions of the identifying diagnostics. But the images were half tones and actual size.) Once I get it done it will make a nice identification reference on a tablet I can carry easily with me. If you like the middle dates then there's the Dan Holmes middle date collection http://images.goldbergauctions.com/php/toc_auc.php?site=1&lang=1&sale=59 Once again every variety and good images. He had a Late date set as well missing only one variety. Same kind of imagery, but you can't really attribute late dates from photos. http://images.goldbergauctions.com/php/toc_auc.php?site=1&lang=1&sale=62
The reason the mint has to make billions of pennies every year is not for circulation - its for these hoarders.
Along with the Goldberg resource, I have found an alternative site: http://www.icollector.com/The-Pre-Long-Beach-Sale_as14916 Another great resource for the rarer varieties from the ANA is: http://numismatics.org
