It sounds logical for the purpose you described. I do have a small reservation on this though. If a Qing Dynasty cover has glue that belongs to 21st century provided that someone needs to lift the stamp(s) then put it(them) back in order to verify something, would it hurt the value of the cover a little bit?
I guess if we follow the process of a typical antique restoration then this is not an issue. Is this considered as a process of restoration even if the cover is not damaged to begin with?
