An outstanding and possibly unique (I'm still hunting for any others!) entrant to the Royal Australian Mint's Mintmark dollar range, instead of a mintmark on the design of the coin, these two dollars have their distinctive mark on the rim!
Issued during the Sydney Olympics at the Olymphilex Stamp and Coin Exhibition, each coin has either "SYDNEY" or "CANBERRA" struck into the rim!
Quite likely the only coins of their type in the entire Australian 25mm $1 coin series.
