Looking at the back of the stamp it looks like a crease but under the loupe it doesn't appear to be so. It looks more like a scratch in the gum or gum disturbance. Maybe an indention in the gum? It's not noticeable as I can't see it on the front and also it doesn't go from the edge of the stamp to the bottom. Would it be considered a scratch or crease? Are all creases noticeable on the front?
So, what does the forum think?
Your time and knowledge is appreciated
Thanks
