I get a lot of my circulation finds from change received from
automatic coin dispensers. The grocery stores in Denver use these,
so the cashiers don't hand you coin change, it just dispenses the
coins in the cup for you. The cashiers don't generally get to pick
out the coins from the locked coin tray of such machines (unless
they had a cooperative manager willing to unlock it for them!)
Coin
acceptors generally reject silver and other non-standard
metals (due to electronic signatures of the alloys), but the coin
dispensers will dispense any coin that's the proper physical
shape, so they
can (and
do!) dispense any coins that
are the same size as the coins in general circulation. I've received
a fair amount of Silver Dimes, dozens of Wheat Cents, a number of
Wartime Nickels, many 1¢ to 25¢ Canadian coins, one 1943 Steel Cent
and even a €.02 (Two Euro Cent) from these change dispensers!

A co-worker went to the grocery store for lunch today and got a
weak-date VG 1925-P
Buffalo nickel in change from one of these
dispensers at the express lane, and she was showing it off
to all of us!

It was yours truly who identified the date,
with a magnifying glass (since I don't have a loupe at work!

).
She almost went into shock because she thought I said "1825", but
I quickly corrected her with "No, that's
1925, this design
wasn't made until 1913!"
