I collect coins in a lazy way, and keep them in old Sucrets boxes. I pick them up as they come my way, but never make an effort. I've got bicentennial and state quarters, the new nickels, Susan B., Sacajaweea, Eisenhower dollars, wheat pennies, Canadian coins (don't ask me why), and assorted Latin American, European, and Asian coins.

Two weeks ago I found a Polish 10 Groszy piece in the dimes at work (just a little smaller than a dime), so I traded it for 10 American cents and took it home. Then last week I got a buffalo nickel when someone paid. Bought that one out of the till, too. I've never encountered a buffalo nickel anywhere other than coin collections before. I found that to be pretty cool.
