Never heard of any circulating Euro coin denominated higher than 5 euro (and anything higher than 2 euro rarely circulates, as they're mostly meant as NIFC commemoratives). While 10 euro coins technically do exist, they're all commemoratives nobody would ever spend, as they're sold as collectibles well above their face value. Do you mean 10 euro cents? Because if it really is a full 10 euro coin, please show us a picture!
I found 2 silver dimes in as many days. The 46 I found in a machine yesterday at the grocery store and the 64 I found this morning at the credit union.
There was only 1 penny in the slot. I assumed it was a mangled zinc cent. But when I pulled it out and looked at it.... At least my 5th CS steelie.
This was a single yesterday. Jumped right out of the tray. Saw it, I wasn't even gonna swipe the tray.
