re: What is the most cash you've seen at once?

3.5 million in commercial vault of local bank.

Vault would process the deposits of large commercial customers like WalMart and Winn Dixie.

The cash would accumulate over a week and would then be shipped to the local Fed Reserve branch for deposit into the bank's bank.

Three guys would walk it right out of the building in large bags. No one knew the guys were carrying a few million is cash.

I always thought the process was incredibly weak from a security standpoint.
