OP is a 5-pin bowling ball of some type. Usually they don't have finger holes, but the size and construction is spot on

Man, I traded a couple to a guy that liked UV marbles more than some old Germans I was interested in. $300 would have to be a pretty stellar example i would think

What's the actual color? Also, construction looks like a visible "single seam" which is fairly uncommon on Euro examples.

So iwe"re saying a dug Peltier? Odd, because it doesn't look like it to me. Trying to think if I've ever seen an opaque lavender base Pelt before..

Zoom in on bottom right for similar

Have you considered Alley? That was my first thought.

White patch on either pole and translucent red around the equator

Pretty sure this is one of those foreign 'mushroom' types

Is that a transparent green base?

Welcome, have fun sorting!

Without seeing more detail, looks like early American to me. MFC or maybe Navarre.

Most likely CAC from the pics.

It's a Foreign transitional with sloppy cut off and cold rolls. Quality control wasn't as tight back then, especially in other parts of the world

Here's a couple more in this group for reference

Yes, came in various shades of red similar to the Foreign transitional. This is a vibrant example.

Pretty sure this is more of a Foreign "figure 8" marble and not Peltier Rainbo.

OP is a machine made with spin pattern imparted by the rollers of the marble machine. This pattern can occur in just about any machine made marble from any manufacturer. If it was Peltier (I don't think it is) id expect the white to be more solid/opaque and less whispy.

^agreed

Fairly hard to come by in the grand scheme of things. Especially in decent shape since they're so darn old and the glass quality (and overall technology from that era) was sometimes questionable. Opaque yellow was one of the colors used, some collectors refer to it as egg yolk yellow. What's the size? most of them were a little over 3/4".

Welcome to the site by the way! Can you share any info you have on the items: did they all come together, etc.

Greiner hand gathered, Germany, approx 1850s. Nice example

Im sure there's some value in those items. A well advertised auction will likely get the most attention (post a link if you decide to go that route). Checking completed auction prices is a good reference (ebay, Blocks, Murphys, etc.) The two yellow/green examples id speculate as unfinished (before being ground to shape) but someone with more experience on these can chime in.

Nice bright colors!

Looks handgathered on my screen, I'd day foreign to USA.

Doesn't look like a slag or transitional to me. Probably a machine made that got some wonky cold rolls (on the rollers) resulting in the pattern.
