Thanx,
No, Neon Zidane, I don't have any lucky tricks. I work in a store downtown Quebec city and I often take care of the money part of the business: take the change from the bank to the store, take the deposits from the store to the bank... Meanwhile, I check a lot of bills and coins, but because I mostly handle circulated items, the bills & coins I find are not always top shape...
It's quantity over quality, in some way... but I won't complain!
