Question Of Regummed Stamps

So I've been watching a Tannu Tuva (another area of stamps I collect) auction and just noticed that it was re-gummed. What are the issues of re-gumming a stamp? Apart from the value being dropped is there any significant damages to the stamp caused by this? Is this just a method to increase the stamp's value?

Not only to increase value but could be to hide faults (Thins)

Bingo!

Treat them as used stamps.

Regumming stamps----is a tricky question !
First many expertizing groups no longer give opinions on gum.
The old method of checking between the perforations can be corrected by using a rat-tail file or a Dremel drill with a fine pin-point sanding drill.
All gum is effected by dampness and most plastic mounts glaze the gum on the back of stamps.
The art of removing gum from a low value stamp and turning it into a gel and then reapplying it to a high value stamp has been perfected.
So who can tell a regum and put their reputation on the line as a expert-----no one

I see. So in short there is nothing essentially wrong with them unless they have clear signs of being repaired. Should I buy a re-gummed stamp? Considering how prevalent it seems is there any defense against it?

I was going to ask the same question, but fortunately, I did a search and found this thread. I picked up a "re-gummed" Columbian 5 cent Mint that, according to the centering, I would conservatively grade as "fine", for $13.50 with free shipping. I realize there are many variables, but does this sound reasonable. The stamp came from CK Stamps. Not interested in the dealer reputation...just wondering if this is a reasonable price for a re-gum, assuming there could be hidden flaws. Larry

At $13.00 not much to lose. Personally I would rather have a Stamp hinged than regummed, and that being said a good 5¢ hinged Columbian goes for around $10.

Thanks for the reply. That's exactly what I was looking for.
