Unused Jet Mail Envelopes

I was cleaning out the garden shed at my mom's over the weekend and found these up on the top shelf. Is there any kind of a market for these? I have done some searching and really haven't found out too much. Any and all info would be appreciated. I thank you in advance.

Ebayer trying to get $25.90 or best offer per pack. Am not seeing any sold.

I looked on E-Bay, too, and didn't see anything either.

In my opinion, the value does not equal the cost of shipping them to someone.

These are not stamps or official postal stationery. Also, air mail is no longer a separate service with the US Post Office so light-weight envelopes to keep down the cost of airmail service is no longer of use. You might sell them to someone at a rate of less than regular plain envelopes, per hundred, but as they are light weight you might find it hard to find a buyer since they are not very durable. My suggestion is to share them with your friends and family to use as regular envelopes, or donate them to a charitable organization that mails things out regularly. I don't see any money going into your pocket from them, unfortunately.

Thanks for the input. Over all, I found 2 large boxes or cases. So I have over 4000 envelopes now. HAHAHAHAHA
I honestly did not know if there was a market for them or anything. Didn't have a clue if I could sell them or if I need to get writing letters. Thank guys! I appreciate your input.
