I believe they're referred to as "cold roll" marks from the rollers not being at the correct temperature to smooth them out. A lot of industrial marbles had this feature (how the marble looked wasn't as important) .

Green Clambroths aren't something I've seen much of.

With machine polishing, some things to look for: -sometimes polishing will open up air bubbles that the polishing compound gets into -on handmades the pontils are usually removed -surface is very spherical and "slippery" -patterns can change (seams can open up) as noted above -colors can change (ie: oxblood) There are other things that can jump out at you, but those are the first few things for me. If it looks too good to be true, or if something seems a bit "off", have a closer look.

Yeah, MK vs. Pelt seems to be a recent hot topic so that may be part of the soft bidding.

Possibly. Oxblood is Red. Aventurine is usually in green or black. It's thought the reaction has something to do with the minerals precipitating from the glass formula/heat, etc. , many colors are possible. I'm sure one of our more experienced glassworkers here, can explain it better.

I believe that color green and oxblood happens frequently, whether intentional or formulation related. Aventurine will sparkle under direct light. In different terms: no sparkle = no aventurine (no matter what shade or color).

Looks more MK to me. Where is Galens hammer?

You're right on your First guess (not a Popeye)! Second looks like a Vitro Third is a chip and not a melted pontil

Solid as in no light shines through it? It's seen a few battles for sure

First and 3rd pic show Akro. Green one in 3rd pic is probably CAC

Nice Corkscrews, appear to be in nice shape as well. Congrats.

@Steph what are your thoughts on these? Single color, bubbly base glass (which already looked to me that way from the first pics). Pelt Bananas? I don't know much about these but would love to see some other pics

Peltier marbles share the trait of a bubbly clear base on certain examples. Bogard (and others) also. Welcome to the site by the way! A lot of knowledgeable members here I'm sure can chime in to narrow things down

Sounds about right. Majority look like cateyes, which some people collect more than I do.

The last pic made me think Imperial, Master, Akro in that order (based on pattern). A lot of manufacturers made a deep oxblood red like this, which is typically what the color refers to rather than the pattern.

Were these all dug from the same site somewhere? A couple have the dirt patina going on.

Awesome stuff, very interesting.

Yes, top ones look Imperial and sometimes can have Aventurine. Nothing beats Aventurine sparkling in the sun (one of my favorite Mike Barton marbles below).

The biggest one is ~ 11/16ths

These might be some.

Nice pics (wish I could do that). Is the marble on a stand or anything

What size? I'd guess Vacor based on the pics, but surely there will be someone else that knows more about those types than I do
