Its the Bullion Sovs that are the scarcest, I had a chance to pick one up about 4 years ago and went for the Proof instead - oh dear!! A lot of the Proofs survived because they were sold in sets and stayed that way for many years - the Bullion coins however - now that's a different story. Never mind, I have a lovely coin that you don't see that often! There are the common hairline marks that you see on this type of "set" coin, similar to the 1937. Mintage of 655 as against 5,501 - and the 1923SA is about 2/3 the Price of the equivalent 1937 - now that's what I call value - well done! Been keeping an eye on the post!! and the weather!!
