Hello,
I just received the stamp shown below, purchased on
ebay. Described as "MINT HINGED, OG VF/XF."

There is no gum on the posterior aspect of the selvage. The hinge mark is faint and the stamp otherwise looks good. I asked the seller about the gum and was told that it is normal for stamps of this era to not have any gum in the selvage area.
Can anyone here confirm if this is correct?
Thanks!
