Second Assumption: Royal Mint practices during WWII were a bit more conservative considering war-time material usage. Third Assumption: Coin collecting in the UK is not as concerned about errors as in the US (and Canada). Here is a 1943 South Africa 3d coin. It looks like the "43" has been either repunched or recut. If that is correct I suspect that was done to extend the die life and conserve steel. Am I even close on my analysis?
