Canada 10 cents - struck on a foreign planchet
This Canadian dime was struck on a small bronze planchet. Dimes usually don't get struck on wrong planchets because most other planchets are too big to fit a dime press. Luckily for us collectors, the Royal Canadian mint produces coins for many world countries, and so a wide variety of planchets is present in the mint. I'm not sure what this is struck on - it may be a planchet intended for an Israeli 10 new Agorot coin of the Old Sheqel series (see my Israeli coin section) but I'm not sure. Interesting.
