Help Please With Small Collection Evaluation US Stamp Sheets

Hi All:

I inherited a collection of three books of US 1950-1965 stamp sheets. I already know from a bit of research that this collection is not rare and is not a treasure trove. However, ChatGPT analyzed photos and said the representative sheet was MNH with clean, intact plate numbers and I do have hundreds of these clean sheets. I'm attaching a front and back photo of a representative sheet-- Scott 1024. One book starts at 1006 and goes through 1139 and virtually every sheet is in exactly the same condition as this sample. Hard to get the photo under the 300mb limit, so I'm picking a small section of the sheet. Hopefully it's enough.

Look forward to hearing your thoughts and suggestions for how/where to sell.

Thanks in advance!

Only good for postage, and then only if you can find an envelope large enough to allow you to affix enough stamps to make the 78 cent first class rate.
3 cent stamps needs 26
4 cent stamps needs 20
5 cent stamps needs 16

Dealers might give you 30% of face value. I donated my full sheets to my local stamp club for the full face value tax deduction.

Except I prefer Stamps for the Wounded: https://www.stampsforthewounded.org/

An organization even honored with a postage stamp.

Agree with above posts. Best idea is to donate to a good organization and maybe take a tax write-off. Using them as postage will be a pain.

Unless some stamps on your sheets are perfectly centered.
Then you might find an idiot who pays 1000% of catalogue value just because...

What you have shown is, at best, a little above face value if you carefully detached a block of 4 stamps with the plate number (the number in the far left corner) to create a plate block. You will see such plate blocks on ebay selling for about $1 - $1.90 with the price of postage either included or not. It comes to the value of each stamp averaging 8-10 cents. Dealers however will pay less than face value since they get many such stamps coming into their shops and their inventories are stock with them (go to Itty Bitty Stamp Company to see that they sell unused postage in packets of 100 discounted 30 percent below face value).

You say you have many sheets. If they are from 1940 to 1990, at or well below face value (the years which are lowest value are those from 1940 - 1980, the height of stamp collecting and overproduction of stamps, and note that many stamps are still produced in excess for the amount used but stamps since about 2010 onward postally used are becoming more uncommon as people use electronic means for most communication - yet it is still not worth actively searching tons of them out to hoard).

If it is many sheets - say hundreds, you could go to a dealer to see if there are a few that have value, but again best to check a stamp catalog from the library and just look through it. Also the Swedish Tiger site has a pictorial search of stamps issued by the US since its inception to about 1940. You could check that just to see if you recognize a stamp in your sheet collection at the site. Those would definitely be worth taking to a dealer but, again, if what you have is like what you have shown, then I agree wholeheartedly with the other comments.

I would add that I had PILES of these accumulated over many years and tried my best to use them up as postage only to run into the issue pointed out in the comments above, no space on the mailing to fit them all. But, another problem arose as well and that was many of these older commemoratives not adhering well anymore. They would curl off the envelopes. We are talking in some cases 70 year old adhesives. Just not worth the effort.

Im interested....your settings is set for you to NOT receive emails

Who woulda' guessed that someone with a username of 'sheetguy2' would be interested in mint sheets. :-)

Though, it is not that the original poster's settings are set to block emails, but that users need 50 posts before being able to communicate directly. He would need to find you at a stamp show or look up your username on ebay to reach out to you prior to obtaining 50 quality posts.
