Interesting, I remember seeing a 1966 Australian specimen set offered for sale and it was reportedly from the Pretoria Mint collection - no other details though.
What year was that?
The Royal Australian Mint sold off a bunch of its collection (1987 or so onwards) including some rare patterns. Bit of a shame I thought, even if it was good that a few things saw the light of day.
What are the Groom numbers for the reverses? I have 157 and 163 denticles for the obverses but I think the different reverses have the same number of denticles.
Seems to be - buyers fees and sellers fees together are now standard, though I have seen some auction houses pay you for the big ticket lots as VickySilver said.
