A few marbles

[Justice70]

Going through some of my finds I found a few marbles scattered about. Not sure which ones I have dug but I don't think all of these are. Anyway, I know nothing about marbles and figured I would post them here in case I have a diamond in the rough, which I seriously doubt. Come on spring time.

I like the black and blue one, is that a metallic swirl on it along with the blue? That silver marble, it's metal, right?

Thanks Cheese. The silver one is metal and the blue and black does not have any metallic swirls as far I can tell. The blue and black one is one of the ones that have been dug I'm pretty sure.

The silver one is a ball bearing I suppose, but it doesn't look like steel. If it had a + mark on one side, it would be a metal marble, but if it has no mark and is smooth all over, it's not.
The black one... I think it's a CAC. Might be worth a few bucks. Lets see what Duffy says. I thought alley at first, but I think it's a CAC.
