Australian/Chinese Bullion?

So far I've been accumulating ASE, Canadian Silver Maples & Austrian Philharmonics....depends on wherever the premium is the lowest.

So...here's a question I hope some of the turdites would help me answer....does anyone hold Australian/Chinese bullion? e.g. Koala/Kookaburra/Pandas? If no, why not?

If yes, why and .......are aussie/chinese bullion coins easy to trade? Just curious...

Thanks!
