On Sunday I placed some quarters in a vending machine. I was inserting them quickly and then noticed the coins were not falling into the machine's coin box. I pressed the coin return and two quarters came out. I inspected the coins and discovered that one was a coin from Ecuador. I have no idea where and when I acquired the foreign coin.
Discovered this today
The Ecuador coin was veinticinco centavos (I believe 25 cents) The coin was also attracted to a magnet.
