Should I be tossing them or would be okay to send orders in them to rid my stock of yellowed ones? (that didn't sound right, but hopefully you know what I mean).
What do you do with your older but still in okay condition but yellowed glassines?

Personally I keep them and use them until they turn brittle and start falling apart, literally. I can't see where the color of a glassine would make any difference, since probably there have not been any stamps damaged due to that affliction alone. Like everything else today, glassines are just too expensive to throw away.

Thanks Mike. That does make total sense. I just have to ask questions as I go along in my new field of stamping.

I have never read of any harm one by glassines. There were some mounts from the 1940s that had a deleterious effect on the stamps sealed within, but not glassines. Since you are specifically asking about using them to send out sold items, in theory, the stamps would not be in any particular yellowed envelope for long.
I receive "won" items in toned glassines all the time and sometimes ones that have several prior usages crossed out.
I suppose there are some collectors who are infatuated with gum and condition who could be driven to donning latex gloves and a medical breathing mask to wear while handling their precious mint, never in the same room with a hinge, stamps, but fortunately most stampers are relatively sane.

The glassines turn brown from the acids in the organic materials used to manufacture the product. Of particular concern is the glue used to attach the flaps. If the glue area turns brown, you should remove the stamps/cover and place them in a new envelope. The APS did a study of glassine some time back, and the study committee does not recommend use of older glassine envelopes.
With all that said, it is just to point out that there is a possibility for damage of philatelic material. One just needs to be careful with older glassines.
I have had the same experiences with glassines as Mike stated, without any problems. I have received old, brown glassine envelopes with stamps in them from dealers since I was a young lad. Never had much of a problem. I have had an issue now and then when the mint stamps inside were stuck together and to the glassine envelope. Extreme humidity can be a problem, so keep the glassines and stamps dry. A no-brainer, yes, but I still see this when stamps were stored in a basement or garage, for example.
Now, where I have seen serious damage to stamps is with older manila stock pages. Often in older collections, including older dealer stock, stored on the manila stock pages, stamps have turned brown and brittle along with the stock pages. Keep an eye out for browning stock pages. Also, acid on the stamp paper and gum will leech into the stock page. I would rather see stamps stored in browned glassines and then the glassines inserted into the stock page sleeves than stamps openly stored in old stock pages.

Charlie, I think you are talking about the old Marlate mounts. They were horrendous.

"... the old Marlate mounts ..."
yes, I just couldn't recall the name. I learned not to trust the guarantee inscribed on packaging from them.

Charlie and Michael,
Thank you so much for your insight on the glassines. I will continue to use them. I just went through a box looking for two countries to fill out a couple of books and found all these glassines. I transferred them to the manila pages. One of these days they will be put into yet another book when I do that country. However they are stored in A/C so I'm not too concerned about discoloring or sticking.

Glassines have become very expensive. I use a lot of them to store duplicates and have been surprised at how much they cost.

So I have some really old glassines and wanted to ask all my buddies here just how long should I really be keeping my old glassines. Yes, they are yellow.
Should I be tossing them or would be okay to send orders in them to rid my stock of yellowed ones? (that didn't sound right, but hopefully you know what I mean).
What do you do with your older but still in okay condition but yellowed glassines?
