Wrestling with British King Edward VII Stamps

I got a few more British Edward VII stamps and needed to fold them into what I already had. When starting that I realized I was lacking some key information about how to distinguish the types of these stamps. I go over the stamps I have, my attempts to figure out how to classify them, and where I ended up on these beasts. This site, UK GB Stamps, has a lot of great pictures that may help you with some of the color identifications: https://www.ukgbstamps.co.uk/index.ph... Thank you to the Stamps Boards Community.
