Questions On Migrating Stamps From Album To Album.......

It would seem it's still around wt1 as I have to pry-on every hinge I try to remove lately...

These were truly awesome stamps.


I have just recently purchased these and I have found that the is just too aggressive and need dobbed off before adherence.



Edit: Added images.

Jerry B et al: One layer; one pass through the gummer (the coating machine that laid down the gum onto the glassine web).

Hi Donald

Thanks for answering.

I have come across other people that were told the same thing about 2 gum layers.

Another Myth Busted.

Just curious about this image taken from an ebay listing for Dennison stamp hinges ... I'm familiar with the red, white and blue packaging (dates back to the 1960s or 1970s) and the green packaging was before that (probably 1950s or 1960s) ... which by the way appear to be of the unfolded type ... but what about the blue and yellow packages? Were those even earlier examples? Would they be any good anymore given how old they are?

Let me add to the mix......... I saw something called "G&K prefolded hinges", and they look like they are from "pre 80s" (my wild guess). What's the story on these? Were they similar to the old Dennisons, or ???

Since 1979, G&K has been a division of Subway Stamp Co.

As I have not used them myself, I can't comment on them first hand, however, some websites have claimed that G&K stamp hinges are rated as "poor" due to lack of removability of the hinges without damage to the stamps.

If you can't get hold of Dennison hinges on the secondary market, there is a Fold-O-Hinge that is considered a decent second choice. Not as good as Dennison, but better than some of the others. The problem is that there have been reports of sporadic success with the Fold-O-Hinge, meaning that some packages perform better than others, so there is apparently a lack of consistency depending on when they were manufactured.

wt1: I am familiar with the green packages, but not the blue ones that you show. The difference may be unfolded vs. folded, as you noted.

Your time frames are correct; the older green packages show a script, cursive "D" in "Dennison" and the later versions show a "D" with a straight slant from upper left to lower right, which reflects a marketing change to all Dennison packaging to show a more "progressive" image. See the 1st picture by I Love Stamps in this thread. The stamp hinges in both packages were the same.

I don't know the shelf life of the hinges, but we are looking at about 40 years for the slanted-D packages and beyond that for the older, green packages. Maybe they are of archival quality. Who knows?

Jerry B: It is hard to imagine that two layers of gum, even if the assumption was correct, would have an influence upon the adhesion of the gum to either the paper of a stamp or the paper of an album page. Adhesion to either paper would, in my opinion, be a function of the chemistry of the gum and the process of removing the hinge. Adhesion is a function of the velocity of breaking the bond and of the angle of removal in addition to the chemistry, but I suspect that only the latter is important in the hands-on, manual removal of stamp hinges.
