Looking through the replies in this thread, I am bemused by the variety of answers and opinions. Just so that I fully understand the history of proofs and VIP proofs, I felt it might be useful if some of you experts could cast your eye over my interpretation of my own coins, based on the advice given. First up is my 1953 Proof Set - all coins still in their plastic envelopes, and pretty much polished both in the field and the devices. Perhaps slightly matt on the busts, so I guess this is a set produced well into the striking run, and not at the beginning when the devices and bust would have been matt. Next is a 1953 Scottish shilling in an NGC slab, which is described as cameo PF 68, and it clearly is, as both bust and lettering etc are matt. Therefore, it seems to me that this is an early proof strike, or perhaps a VIP strike. Lastly, I have a 1937 set, in which both the Crown and the Scottish shilling have a cameo finish. All the other coins in the set are highly polished over the whole coin, and exhibit no signs of frosting or a matt finish. My conclusions: clearly the crown and shilling are an earlier strike or a VIP proof, whilst the other coins are very late strikes, as there is no sign of any matt finish. Therefore, either the crown and shilling were omitted from an early set and were 'found' later at the mint and 'married' to later coins to make up the set, or the set has been made up by a collector bringing together individual coins to complete the set. Does all this make sense, or have I misunderstood this thread completely? PS: For what it is worth neither my 1950, or 1951 set exhibit the slightest sign of matt finish or cameo effect, which I presume is correct?
