Interesting, it is most likely a repop, but cool find nonetheless. If you want to do some research on it, it is a British design that dates back to the 17th century, the obverse portrait is of Oliver Cromwell. There were 3 different denominations (shilling, half crown, and crown).
What's on the other side? That coin is still a keeper. What I would do is start a thread in the world coins forum and ask to identify this coin as fake/ or real/ and or what is it. Show both sides in photos.
Not a coinstar reject find but I was at the bank earlier today dropping off some searched coins. I noticed in the teller's tray, sitting in the half-dollar slots, something "silverish" that was smaller than a quarter but larger than a nickel. I asked her what it was and she said "something foreign" and let me look at it. I didn't recognize it at first but she said I could have it anyway. Got home and looked it up and it is a 2010-B (Bern) Swiss 1-Franc coin. Made of copper-nickel with an image of Helvetia on the front and the date/denom on the reverse.
Haven't been to a Coinstar in weeks. But have found 57 cents at work. Today two dimes, a 2000D road warrior with a decent reverse and an unknown but zinc road warrior. Generally find something every work day.
Stopped by the coinstar at the grocery store last night... around 75 cents in random modern coins, a one euro and half euro, and a 1950 silver quarter. Definitely one of my better finds over all.
handful of foreign coins today: 2002 Cuba 25 centavos (first ever Cuban find) 1989 Dominican Republic 10 centavos 2003 Canada nickel 2003 Canada cent Japan 1 yen
2 arcade tokens and 30 cents. I throw in the arcade tokens with the candy bars on Halloween. I find ALOT of those metal detecting.
Thursday I found nothing at work. Yesterday got me 11 cents. I am not finding silver or foreign coins this way but I am getting spending cash out of it.
Found a presidential dollar in the coin machine reject tube at my bank yesterday. Actually walked away from the bank $1 richer!
