What Type Of Stamp Mounts Are These?

I picked up pages with mounts like these and notice what they did to the page.

The mounts are constructed with a piece of black card stock with a plastic overlay folded around on three sides so top or side loading depending on stamp. There are two strips of adhesive but not sure if added or came with mounts.



Anyone know what type of mounts these are? The collection ends around 1976 or so guessing they date during that period.

These are PM(Protective Mounts) brand Marlate Mounts of the 50's to 70's. Horror equal to or greater than Crystal Mounts in their own particular ways.

When I used to buy large WW lots I would run across collections with these mounts sealed on all four sides. As Randy said they were an absolute horror show to rescue stamps from. Lots of profuse swearing and intake of alcoholic substances.

Luckily, you did not notice all the ways Marlates can ruin a stamp. Carefully remove all stamps from these. They were a clever idea that too soon proved to be absolutely non-archival.

When I come across mounts like this, I use a small craft knife with a sharp pointed blade to carefully cut open the top or bottom of the mount. The sharp blade can then cut along another side of the mount to allow the plastic to be opened so the stamp can be rescued.

Like Crystal Mounts, Marlate Mounts were a good example of how companies sometimes experiment on their customers without having done sufficient testing themselves. Besides ruining album pages, how many stamps were ruined by these awful mounts, I wonder?

Yep, it requires surgery to extract carefully. The other collection had them sealed on all four sides.

I liked the comment in the other thread.

So, there was a level of hell BELOW the one where Crystal Mounts were made?

I've heard others refer to these as "body bags", for stamps.

A great idea at the time, every time someone posts about a current great idea (modern adhesives, sheet protectors, cheap 'acid free' paper), we should recall threads like this.

Thanks for the ident on these mounts. The #11 Xacto blade, when generally new, makes short work of these when you can carefully get to one side of the mount farthest away from the stamp. Rescued a two volume Poland collection that way, including lots of earlies, found it all Mint Never Hinged. Never know what might be hidden inside!

To be consistent, we could add hinges as the mounting method that has damaged the most stamps but seems many accept this.

Of course using the right hinges or the right mounts will reduce the risk or damage. Some aspects add risks to varying degrees but hinges are usually a sure thing.

Marlates have damaged more stamps vs. hinges in proportion to the numbers used.

You can hinge a stamp and never show a trace of leaving an indication being hinged? My guess is that does not count as damage. Everyone has a different standard.

The same discussion could apply to writing on back. If you have 2 stamps - 1 hinged with no writing and 1 never hinged with writing. Some view the writing as more of an evil than a hinge mark.

Here is another collection using same mounts on White Ace pages from another dealer. The pages do not show any side effect from storage themselves.

I usually extract while mounted on page then remove mounts.

The scan highlights the yellowing more than it appears.





I will scan the pages later then offer them to anyone who would want them.
