Three odd ones in a jabo lot I grabbed.

Is the small one a bullet mold?

I think that the two darker ones are contemporary—made to look like old—the larger one may be a WVS.
No “bullet molds” here at the least--imho.
I appreciate all opinions and wish for some more.
Nice marbles and size matters here.
Marble—On!!

The smaller one is 5/8 the other two are 3/4. No seams on the pink one that would give it away for me

x2 on the two left as contemporary.  The swirl unknown to me.

Different pics might help, I think I'm seeing a lot of reflections 

Smaller one obviously looks like guinea, what color is the base glass?  Seam looks tighter than what you'd normally see on bullet mold (and most contemporaries).  but the base glass is throwing a curve.   

Is that a pontil on 2nd one? (first pic)?  pattern looks abstract enough, could be contemporary.

3rd looks like Veliliglass to me

Base is opaque, black. No pontils, both of those two are solid opaque black. Only the smaller one had the seam line

Could they be clay contemporarys?

If they're not glass, I'd guess polymer - pretty tough to get that sort of finish using clay. If polymer, they should feel quite a bit lighter than a glass marble of the same size.
