How To Unstuck Mint Sheets

Received a collection and am trying to put them into Albums and Glassines to preserve the stamps. Had some mint sheets that are stuck together. Is there a way to unstick the mint sheets? I saw that you may be able to use stamp lift fluid or a stamp lift too using condensation (if I remember right) for individual stamps. Are these my only options? Trying to preserve as much as I can. Thank you!

Personal Opinion.
After drastic results using your suggestions,
only one course of action.
Soaking in cold water until they separate.

Using your suggestions, you only need one failure to reform, watch as you gently separate some frozen stamps, and see the stamp face paper lift of the sheet below. (esp with offset litho stamps)

Thanks, rod222.

Lave,
being as they are sheets, I caution you to be very gentle with them,
otherwise they may part at the perforations.

The next problem, is the gum.
When soaking a sheet, one does not have the ability to remove all the gum like a single stamp.
All workability is lost through fragility.

I would personally use a "drying sandwich"
after removing from clean water, place on a dry cloth and pat dry

Then place the sheet on an appropriate sized FREEZER BAG
(Gum side down) itself on a sheet of clean paper, and a final clean sheet of paper on top.

The sandwich is then placed in an appropriate sized book
and left for 3-4 days

The sheet should come out as flat as a halibut, and easily removed from the freezer bag.
Failing to do this, the sheet may AGAIN adhere to paper during the drying process, and you have to start all over again.

Lave,
Reading your first post, I don't get any idea what era these sheets are from and how solidly they are stuck - and thus what level of effort is reasonable. More information is needed from you for anyone here to give any reasonable advice.
Specifically, if these are pre-WWII, then they deserve some effort. If they are post-WWII, then they are likely replaceable at less than face and can be soaked without much regard to keeping the sheets intact as no-gum post-WWII sheets are not going to have any demand, etc.

Hi John… these are 1980 mint sheets. Finally figured out how to upload the photos. Does the value differ if it has the gum or not since these are newer issues? Thanks

Thanks for the advice, rod222. Will look into it.

Basically, the value of the vast majority of recent mint stamps lies in their potential use for postage. This will be a percentage - say 50%, but it varies according to the size of the denomination - of face value. If you soak these or separate in them some way that disturbs the gum, the value will be still less, because using them will probably require faffing around with glue-sticks

Oh boy!
I empathise, that is not a good look.
THAT my friend, is a major undertaking.
Never had to soak anything that dense.
Good Luck!

That much gum in the soak water is going to be an issue (gum getting all over the stamp fronts). It might require running water over a period of time (a tub with a trickle going in and a trickle going out).

Good idea Don,
personally, I would be making a dedicated screen.
1 inch square pine, made into a square /oblong, a little larger to fit the sheets, staple plastic insect screening, taut.

One can lift the sheets in and out of the water, without damage whilst soaking. as a sort of sieve
Using your method as well

I have dealt with stacks of modern mint sheets in the same condition that came in bulk lots. They went into the trash. The juice is not worth the squeeze.

That's been my experience with cigarette cards from the 1930s, which were printed with gummed backs. Packed together, left in a box in an attic or shed, a solid mass for the purchaser of today. I now put them in the recycling.

Thank you for all the inputs. I'll give it a shot and will update afterwards. Unfortunately, that's how it came with. I will salvage some of the stamps that are not stuck (around the edges) instead of maintaining it as a full sheet.
