Australia 1993 $1 Landcare Silver Proof Continuous Milling Brisbane Coin Fair Release ERROR!

This silver coin, issued in May 1993 at the NAA Coin Fair in Brisbane, has a continuous edge milling and was distributed, encapsulated, with a numbered certificate from '0001 to 5000', in a presentation case protected by a special coin fair issue presentation box.

A very small quantity have been found where the number on the certificate of authenticity is missing. Collectors are willing to pay a hefty premium for this error.

Deteriorated/damaged boxes as usual.
