The Magdalen Islands had only one coin - a 1 Penny token issued in 1815 by Sir Isaac Coffin.
The obverse of the coin depicts a seal on an ice floe. It is inscribed 'MAGDALEN ISLAND TOKEN 1815'. The reverse of the coin depicts two gutted fish similar to that depicted on 1/2d. tokens from Prince Edward Island. The reverse inscription is 'SUCCESS TO THE FISHERIES', which refers to the fishing industry essential to the islands' economy.
This coin is very sought after by collectors of British Empire coins, not just those of Canada, as this piece is very rare.
