I searched just a bit more coins the last two nights.

160 small dollars had one mint set dollar (1981D).

1,800 quarters turned up one Canadian, one US nickel and an angel medal (man, I've found a lot of these).

1,200 dimes rounded up one silver Rosie (1957) and one Bermuda 10¢.

720 nickels got me three Canadians, one Thai 1 Baht, one US dime, one semi-key Jefferson, the 1955, and perhaps a 1967 SMS (very difficult to discern whether or not this really is an SMS or is just super shiny).
