I used to get masses of coins to sort and count when I had three launderettes. I started simply by hand, moved to weighing having hand sorted, then had two generations of mechanical sorter / counters. Neither were perfect. Frequent unjamming sessions.
With £1 coins I got to the stage where I could grasp a fistful and weigh them and 99% of the time they were correct (20 to a bag)
I used to get a fair quantity of forgeries - some obvious - others rather crude - I think I still have a bag of forgeries somewhere. Then there were supermarket trolley tokens in several varieties - some passed through undetected others didn't.
Once in plastic bank bags they were grouped in cloth bank bags or seal pouches and lugged into the bank - glad that's over - thinking about it it's probably why my shoulders are so bad !
