65k. I worked at a pizza joint and one of my jobs was making the deposits a couple times a week. So it was a deposit bag of cash after a couple days where the manager hadn't run the drop.
US currency as mentioned? None
Otherwise I dont know, I've done the banking for my workplace a number of times but I don't exactly stop and count that....
I believe I've held close to $2000 the time I was taking cash out to pay for my dog though.
