Most boxes were MWR, when I get CWR I hand count ( some over, some short, evens out ), the bank bags that's something else, but that's where you can get a full collection. NO, I don't keep track, but if I do notice a big shortage then I notify the teller at the bank.
Icewing: however, in an old post of mine, Jan-2017, I pulled 98-silvers from one bank wrapped box (65-mercs, 33-Rosies),
imagine what the numbers would have been had they been in a bank bag !!!, enormous. Ya can't play the game unless you try, can't win the lottery unless you buy a ticket.
