I have only ever found one of these bubble coins; scarcer than 'wavy 2' from my perspective! I received two from forum members (thank you) but one has gone OS as part of an international swap.
Anyway, I would like to get some more.
If you have some spare let me know what you might be looking for.
I have a good number of 2008 20¢ gap, 2004 bighead which might be good swaps. Or, maybe some low mintage years; 1971 20¢, 1993 50¢?
Perhaps some 20¢ commemoratives -UN or Bradman. Maybe even some 50¢ commemoratives? And, I do have a few good $1 coins (including some Last Anzacs found circulating).
If you are interested let me know what you might be seeking in exchange and we might be able to strike a deal.
Thanks,
Jeff
