I recently bought a US collection from one of those auctions and I'm breaking it down - some to keep - some to sell on
ebay. The previous owner's identifications have been pretty good, but finding plenty of mistakes. Anyway, came across this nice looking page but I have no experience with confederate stamps at all. I took a quick look at my Scott Specialized catalog and I am truly lost. Stones? Is that like a plate? The red one used is more valuable than mint. Does that cancel have any chance of being legit?
Like I said, I have no background in Confederate.
I'm looking for any guidance you might like to provide to point me in the right direction. Are there some good documents or sites that have guidance for confederate identification? I'd like to learn enough to at get a start at this. Thanks in advance.
