Couple of questions about these in case anyone can help
Rogers in his "Centenary" book says that very few of these stamps were used postally with most mint or CTO
The Scott catalogue shows virtually identical prices for Mint and Used when I'd have thought used prices would have been higher due to scarcity
Is this another example where catalogue prices are unreliable?
Also for M6 the 1c on 1c official two stamps are listed
M6d and M6e
Only a Used price in shown in Scott no mint price
I have a mint copy of each so have no idea of their possible value
