I hope you're all right.
I have a piece of cardboard with 3 stamps attached. Two had a strong seal, so I decided to take them out by putting them in hot water .... As soon as I heated the water, two left the paper, but the third one didīnt came off ......,
I returned the card with the stamp in the hot water, but it didn't come out ...
I examined it better and saw that it was not a common seal but a seal printed on the paper and without perforations, being an integral part of the paper.
I would like an opinion if this printed stamp has any value greater than the catalog stamp
(Scott 619 / Michel 632).
Can someone give me a light about it?
Thanks a lot.
