Gold Coast
Gold Coast is a city on the East coast of Australia. Australian royal mint has produced these coins to commemorative the 150th anniversary of this city (Gold Coast Sesquicentenary). 1, 5 and 10 Dollars coins had been made on this event.

Note: Not to be confused with the old name of Ghana as Gold Coast.

 

I purchased my 1 Dollar 1992 copper coin having 33mm diameter with unreeded edge from Chaim Dov Shibolet (shibolet@yahoo.com). $5 in nickel and $10 in brass also exists.
