CHARLOTTETOWN -- The Royal Canadian Mint has unveiled a gold coin to commemorate the 150th anniversary of the Charlottetown and Quebec Conferences, events that helped lay the foundation for Confederation.

The coin features the fleur-de-lis, the English rose, the Irish shamrock and the Scottish thistle -- the four major European settler groups represented in the provinces at the time.

It was designed by mint engraver Matthew Bowen, has a face value of 50 cents and will have a mintage of 7,500.

It sells for $129.95.

Held in 1864, the conferences in Charlottetown and Quebec City were attended by the political leaders of British North America who agreed to form Canada on July 1, 1867.
