In my quest to break down collections for sale, I've come across a bunch of Revenues. I have very little knowledge in this area and I'm trying to learn. What I'm looking at are mostly perforated first issue stamps and they seem pretty straightforward to identify. They are used, or when they appear unused, have no gum. I'm assuming they are all used except this one. It appears to be unused with original gum (hinged).
I have two questions. 1) There is a complex design on the gum. Is that normal? 2) Do OG stamps command any kind of premium? The cat for the used stamp is $1.
