Yes they get rejected for wrong metal. (Like the steelie.) I have found them under the lip of the machine on the FLOOR more than once. And one time, this is hilarious, someone left it on the shelf. I can imagine them taking it out, and putting it back in again and again and again, until they just gave up and left it on the shelf.
Today: CWR $5 cents - nothing CWR $20 5 cents - 41-S, 43-P, 44-P, 45-P, 45-S, 64 Canadian and 65 Canadian pretty good haul for small number of rolls with the 5 cents
Yesterday 2 dimes and a penny. Today 37 cents, a Euro dollar and a pressed "coin" with dragonflies on it. It seems home made and not to be a coin as it weighs 2.0 grams. Too bad there's no way to cash in these Euro dollars.
Pile of foreigns on the shelf. Some arcade tokens and a fractured Lincoln. I will check with my loupe if anything is unusual. OK this is what I found: 1 dinar Tunisa 1976 1 dinar Tunisa 2011 50 centavos Argentina 1994 2 Euro coin Assorted Mexican and England coins 1 China Yi Jao ( 3 of them) 1 dirham United Arab Emirates
It gets rejected (wrong metal) and the people throw it away. I got one like that once on the shelf. Canadian nickel today.
This was my Coinstar find earlier this month! Second time this year so far and someone just left it behind in the catch below. Sterling silver ring in this lot as well as that 1973 Lincoln cent which looks to be VG. I'm checking that machine every time I visit!!
My biggest haul ever in a grocery store where the Coinstar is near the service desk and hard to stop and check - 2 Euro, 1 Euro x2, 20 Euro cents, silver quarter, 2 silver dimes, and 2.93 in other us coins. I suspect that because of the Euro coins on top some people looked and passed.
1940 wheatie on the shelf. 1000 dong Vietnam. The 1999-D is smaller in circumference and doesn't look like zinc, but the weight was only 2.2.
