Cool bunch of finds, especially that beautiful '46 SILVER quarter!! That's an excellent find. It's worth quite a bit more than 57 cents.
Are any of those pennies wheaties?? I can't read the dates from the pic. And what year is that nickel??
You may be able to look that button up or ask here. Someone can usually fill in the blanks around here.
I actually found a Baltimore County Police button last year (thought it was gold at first but alas, it was not). So far, it's my coolest button find. I think yours is pretty cool too.
I don't believe cops lose too many of those so they don't turn up often.
Congratulations.
