I know this conversation has cropped up before but I would like to seek clarity on the issue and I know this is going to be a specialised catalogue answer?

Stamps which are mint but without gum is this a true description?

I recently sold a stamp not knowing it had no gum and the buyer wanted a refund and when I got the stamp back sure enough it was not gummed. Something I now check I might add but are stamps issued not gummed or is this a collectors handy work?

I understand that some collectors wash gum off stamps because of the damage that gum can do but are stamps issued without gum.

I know most "C" category stamps can be gumless but that is probably because they are fake anyway? The other problem is, IF stamps are sold gumless how the heck can you tell if one has been washed or not?

Surely when taking gum off a stamp there must be signs this has been done?

I also take it that a ungummed stamp is worth less if it is supposed to be gummed because the gum is an integral part of the stamp!

"C" category? If you mean Cinderella - very many were gummed.

Some postage stamps were issued without gum. The catalogue should tell you. If issued like that then fine, no reason for a refund. If gummed then M or UM (=MNH for the USA) would be an appropriate description. Stamps which don't have gum but should are definitely worth less. Depends what it is, but this is generally true.

One to look out for are some of the Commonwealth EVII / GV high values which were used for revenue purposes (so often cancelled with a pen stroke) where the cancel has been removed or bleached out giving the appearance of "mint no gum". Sometimes too these have been regummed. It may be possible to tell if the gum goes over the edge of the perorations and is visible on the perf tips or edges. Almost all stamps were gummed before being perforated!

Lol yes you got the "C" category, I have loads of them un gummed and funnily enough, you know we talked about perfs not matching up horiz and vert, well on these 1908 Canada Quebec centenary stamps its the same with them as well so it does make it difficult to know if they are fake or not, in my searches I have seen many blocks and the perfs are all out of line or sync. Also with these they are all suffering with print shift, some more extreme than others and I shall be making a post about these later. But again is why I asked this question because there seems to be a lot of these without gum around?? I just wonder if they have come off envelopes and in that process the gum getting wet they just take it all off?

And in my heart I knew you was already going to say specialised cats will tell you if they were issued gummed or not.

Thats interesting to know, I suppose the process is easier to gum whole sheets before perfing other wise you would have glue dripping through the holes??? So is gum applied before the main print run, I.E rolls of gummed paper, then print run, then perf run.

I suppose re gumming would be using a PVA solution but even still getting quantity must be hard and even and again would this not effect the stamps front? Spraying glue is far easier then brushing but I would imagine pretty hard which ever way you try.

I was a bit miffed thats all, that I did not see or notice but it is something I just did not even think about and unfortunately on this occasion I never took reverse pics because it was mint had the back had problems as most old stamps do, I normally take pics. Another lesson learned the hard way!
