. By any chance would you post an image of all of these so I can print them out
I'll give it a shot, no guarantees.
TIP: I think Scott has stamp appraisals in the front Preamble.
that show classifications.
my personal opinion......
Basically, a Stamp is MINT as it comes fresh from the perforator, and distributed to Post Offices.
If, by some circumstance, the mucilage (gum) is affected in any way, heat, hinge, fingerprint, moisture.
Then it is MINT hinged or MINT disturbed gum.
Then if it is issued with gum, but missing (soaked) then all lower hierachy is "used" no matter what.
Your stamp is definitely used, but nice perf teeth, clean,
I would certainly use, or until a mint stamp comes into possession.
