What are these?

I think maybe welddigger is right on the money, they could be whimsey's.
Often the glassblower would have a blob left over at lunch time and to clear the stem they would make all kinds of whimsey's, marbles, eggs, canes, paperweights etc, etc.

I agree I believe that they are some type of whimsey or end of the day item but I am just trying to find out for sure. Are there any marble collectors out there?

Look like newer eggs that are showing up now days.Not end of day stuff.

I think I may have found the answer I found this on ebay 9 VINTAGE END OF DAY GLASS TEARDROP MARBLES maybe this is what they are anyway.

Not! There is more crap on Ebay than a Carolina Hog Farm. Worst place you can resort to to get an I.D. These are new ,modern glass from China.

They could be sock darning eggs. They were slipped inside the sock to let the darner repair the hole.

They don't look like anything I would recognize as being old. They aren't marbles though and neither were the ones on abay

Those look like some kind of decorative egg used on Easter. Those sometime turn up in Bottle dumps...

Geez, I kept reading this post thinking.. someone else say it.. I don't want to. I don't want to be inappropriate here or get kicked off but...

If they are Asian made, the chance is pretty good they could be some type of ben-wa balls. Some were elongated instead of simply circular like a round marble.
The fact that you found several together also makes me wonder if I could be correct. Usually, several of slightly different sizes were used together connected by a string.
They were used for both sexual stimulation or exercising to strengthen the kegel muscle

Here is a good site for explaining their use and examples that looks to be like these only made of jade instead.
Notice the shape and sizes as well for comparison purposes.
