Since I started chemo I have a ton of time to pour over a lot of reference material that has been plaguing me for eons but I was reading Vol.II. of Brookman's Postage stamps of the 19th century on the Banknote issues, especially on the Continental secret marks on the 15ยข Webster (Scott #163) from plate #31 and I'm on board with their reasoning about the worn out die/transfer roll [illustrated below] but since this reference is from 1966 or thereabouts, and I was sort of hoping to maybe find if anyone has elaborated on this with a more modern take on it or proofs an examples to the contrary, that kind of thing. Where would I look? Any good reference material that expands on this? Thank you very much. -Jeff
