The Royal Canadian Mint will unveil a new $100 gold coin in Charlottetown today that celebrates two key moments in Canada's development.

The coin marks the 150th anniversary of the Charlottetown and Quebec conferences which laid the foundation for Canadian nationhood.

In 1864, officials from Nova Scotia, New Brunswick, P.E.I. and the Province of Canada (Ontario and Quebec) met in Charlottetown to discuss a maritime union.

It was at that September meeting where Sir John A. Macdonald proposed the idea of uniting all colonies from east to west.

A second meeting a month later in Quebec City produced a framework for the British North America Act, which ultimately led to Confederation in 1867.

The top half of the coin features the Charlottetown Colonial Building, now called Province House, as it appeared in 1864. The lower half depicts the Quebec Parliament Buildings where the Chateau Frontenac now stands.

The mint‘s website shows the coin will retail for $599.95.
