Bunch of old marbles

My friend Mark found these at a few different spots.  A very old dump, a 1940's house, and various other locations.

We have a few favorites, but don't know much about marbles.  If anyone can help point out the one's that we ought to research, we'd appreciate it.

Third picture the two bright green will glow if you put a black light on them and the yellow and gray in the same picture needs reserched. That one looks like a christiansen marble and I dont recall ever seeing that color combination,but then again I dont have a lot of those either.

i agree on the christensen id...

Thanks for the help, Wheelerite and Duffy!

We'll do a little more research on the possible Christianson.

We know nothing about marbles, but based on Wheelerite and Duffy's comments about the yellow/grey, do you think that there is another Christensen in the first pic, near the bottom left....the yellow/red swirl?

if it corkscrews....akro....looks like it might by that pic....chrissys  usually have a visible flat cutline...

Couple more pics.
