Bill D-
My parents, in the 30s, had a government job that entailed staying in various cities for a month or more at a time. To pass the time after dinner, in their hotel room, they would sort through rolls of pennies, dimes, and nickels obtained from the banks. They would sort the coins by date and condition, and got complete penny (1909 on) and dime sets, and I think most of the nickels as well as some better quarters and halves. Still have them in a steamer trunk, along with stuff I have added. I think it would take 4 men to shift the weight.

I guess once the collecting bugs bite, the illness is permanent. Still working on a Japanese postage stamp collection, and Canadian coins.
