You seem to be keeping up with a decent world coin collection. I'm struggling to move my interest outside of British, but Austrailian coinage seems to be on my mind more than most. This month's additions for me. 1951 Crown, prooflike in red box. 1962 Half Crown - polished flan, BU lightly toning, unrecorded, Davies die pairings 2+B. Came in a sealed polythene wrap, previously owned by a retired Royal Mint employee. It seems there are more polished flan varieties for other years out there, 1961 being the most prolific. I have seen one other listing for a 1962 polished flan that has been sold. I have heard from others, 1955 half crown and a 1950s sixpence with polished flans.
