They tell me it was a long wait in line to get the counterstamp coins. I had a mate fly down to visit the show and waited 90 minutes in line! Then they only allowed 3 at a time.
The Brisbane counterstamp would be one of the lowest mintage $1 coins with less than 4000. Be interesting to know just how many. I managed to buy one from Oztion over the weekend. You see them slowly popping up on Ebay too but not at the same rate the Sydney counterstamp did.
