Had a quick half hour in between a few things today, found $3 what was interesting was that both 50c are the same year ? One with a lot worst condition than the other. The $2 is well corroded as well. Good depth find somewhere between 15cm + in semi rocky beach area/sand. Found a few thumper sinkers also. Gave them to a couple of local fishers who looked at them like WTF did you need to hold to the ground ? They were like snapper sinkers in a river ?
Also what do you guys use to soak/clean coins like these ? Not sure they will take the 50c and $2 like it is over the counter at shops ?
Electrolysis perhaps?
Works great on old silver coins, but dunno about modern coins.
Otherwise just farm them out when making small purchases one or two at a time. (Say "got given this in my change yesterday...still legal tender.)
Otherwise just use use in parking meters, car washes or vending machines....no pesky human to give you funny looks.
