how many wheats in the bag? Could it be possible that someone bought the bags, sorted for wheats, and then brought the bags back to the bank? Maybe it just happened to take the guy that long to sort them?

I doubt 40% was average when those bags were dated. You probably just hit a nice copper vein. Some of the longtime hoarders could probably give a better assessment, however.
Recently I got a box of nickles from my main bank dated June 7, 2007, so apparently some coins do get stowed away in the corner of the vault.
