Rejected Coin

[jay]

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.
