Bluenose 158 Gum Side - Og??

Hi folks
Wondering if this bluenose block was re-gummed..is anyone able to verify with just an image?
Thanks

If I remember correctly one way to tell if a stam is regummed is if it has gum on the perforation tips of the front?


Waiting for somebody knowledgeable to come along....

Well, it is difficult to see just with a picture like this. Here are some pointers you can check:

- Check if you can see the printing "embossing" clearly. If not,either it is regummed OR wet printing (there was none on this issue I think; I got a 122 once I first thought was regummed but it was really a 122b wet printing). In wet printing, the gum is applied after the printing, making the printing "embossing" less clearly defined.

- With a magnifying glass, look for gum on paper fiber on the stamp separation or of gum accumulated on the perforation. Stamps are gummed before perforating, so the gum is supposed to be distributed evenly even at the perforation. This is why regummed stamps are often re-perforated. Check the perf meter also.

- If you can compare with an other one, look if the gum is the same color and if it has the same finish.

- On older stamps like this, you usually can see through a magnifying glass that the gum is "cracked" but without any damage to the gum. If there are no cracks, then it is suspicious.

- If the regumming is really poor, you might see brush stroke on the gun, or even brush hair left there. But this kind of regumming is easy to spot.

The really good way to tell if it has been regummed is to have the stamp on hand. Maybe with an insane resolution scan it would be possible to maybe tell if it is regummed or not. but I think it would not be conclusive.

I am no expert myself, but it is the tricks I got for myself. Hope it helps.

Edit: I just wanted to add that if all of those do pass, it may not means that the stamp is NOT regummed. Some people are very good at forgery. An evaluation by an expert (having it certified) would get any doubt out of the way.

By no means a pro but even looking at your scan you can see perf fibers as well as a good impression of the bold image text can be seen throughout. Margin block of 4 and although not VF centering would still be pretty pricey. I would say MNH but as stated above some regummers can be really damn good. Although no signs are visable, if anything maybe re gummed over old hinge mark but a MNH block of 4 Bluenose is not so rare as to think its unlikely to find these. Just my 2c

stampguy...I would think that if it is re gummed that you would not be able to see the front of the design of the stamp trough the new gum...You can on yours

Looking at the top row of perforations I am initially suspicious of a regumming as the row of holes seems non-gummed.

However, tilting the stamps in a good light (sun light) will show whether this is just bent perfs (all along the top) or shines or not.

The bottom looks good though. As mentioned, hard to tell with the slightly out of focus picture / scan. Needs a higher resolution (600 dpi scan to see if the top perfs (and bottom also I suppose) are showing ungummed fibres from pulling the stamps apart.

Oops, noticed the bottom of the stamps are held in plastic. This could change the colour perceived.

But what of the left and right outer side perfs colour change?

Thanks for all the help everyone!
Some very good info and advice...
