A couple more candidates for the list: The olive drab Beer (Propeller) can, and the dull grey Fort Pitt.
Andy (Hemmings) raised a good point on "lost" cans also. I'm not aware of anything #33 owned the only good example of, but others may be.
I suppose we could list Gretz Bock J-Spouts and Crowntainers, as I have copies of shipping invoices for both. None are known to exist as far I know, but thousands were shipped to the brewery.
The line for condition remains a bit fuzzy, but I'd like to address the inclusion of the Jolly Scot. I had that can, the Trenton and the pair of 10 oz. J's in my possession for a short time years ago, and the photo below was taken at that time. The Jolly Scot and Trenton were widely believed to be the best known examples at that time, and both are pictured in the USBC and the Class Book. Both look better, and in my opinion more representative of the "in-hand" appearance, in the USBC. I didn't put either can forth for the list. I don't have an issue with them being on, or not on, the list, but the grade is similar enough that I think both should be on the same side of the line.
Additionally, I did put forth the Gretz J-Spout, and that bears explanation because the Class Book example looks very nice. Dale Rogalski had that can for sale about 15 years ago, and the can apparently remained full for many years and leaked before it was found. The can has several holes in the back, and is discolored around the holes. It also has a new bottom that appears to be from a hairspray can or something similar.
