Hi,

I was wondering if this stamp has been damaged with spores? Do you think I should isolate this stamp from other stamps and put it in a dedicated pocket/envelope? I was told this was the first issue and the gum contained too much of the starch (not sure this is the correct word). The stamp is of early 1940s (USSR).

Thanks in advance.

Opinion.
Gum disturbance from a humid environment, damp album page or glassine.
I find with mine, a soak in cool clean water, rids the damage, providing the new environment is good.

I have had duplicate with similar damage, remain OK for years in
the duplicate box providing again, the environment is dry and stable.

Still not a good look, use as space filler till clean ones arrive.

Damage like this usually starts at the fine hairs of the perforation teeth, or at the gum.
Good Luck.

I collect Russia and had never heard the starch thing before.

Well, Russian stamps before 1960 had an organic gum applied to it, not sure if starch was one of its components though. I agree it's certainly a damage but the question is rather if this is kind of foxing, mould, spores - something that can move to other stamps or if this is a permanent issue, not spreading further.
