I just found the other kind of H&C mold in the Christmas Island 2.50 chip. See the scan.

This is a small place that I believe is technically in Australia.

I got my second one from Bill Akeman on eBay and there's another lot closing today. If you don't have both, you might want to see if the mold you need is the one offered. These are fairly scarce, going for $30-40 in auctions. I hope JerryW didn't have too many of these [g].
