A Brief Technical Note

All the above images are scans (not "photographs") of proof coins. As such, the mirror-like fields of the coins have scanned as black, when in fact they are bright and highly reflective.

All of the coins, except for the 50¢, are from the 1991 proof issue - chosen because this was the last (i.e. "most recent") complete issue - complete including the 1 and 2¢ coins.
The 50¢ (and the common obverse) is from the 1986 issue.
The 1991 50¢ was an atypical commemorative piece.
