Better pics might show a ground/faceted pontil, which is what I'm interpreting from the bottom right pic. Probably an early German hand gathered.

Agreed, Vitro (with a slim chance of Pelt) on the right. Left looks a bit wonky. Have you tried a flat (non-textured) background? Gray usually works best for my camera

My guess is a rock tumbler or some time in the river or aquarium

Polishing a marble will sometimes change the appearance/pattern, I think this might be what happened here

Alley would be my first guess

Sounds about right, appears to be nice spacing, nice color, nice condition. More likely German origin...since I can't say I've seen cane cut swirls with early American provenance? But I sure haven't seen them all

Pics 6-8 look like they are handgathered, which makes them a bit more interesting (to me anyway). But condition on the blue/white is shot. Hard to believe some of them survived in that condition without busting into pieces. Must have been somebody's favorite.

Interesting to see the Canadian connection (patent).

There are probably a few answers to those questions and some of the terminology varies. For me "jellcore" would be a solid core except the core is translucent like jelly. "ribbon core" is one (maximum two) flat ribbons of color, thinner they are the more "razor" they become. Once you get more than two ribbons, those become a "divided core". Some "solid cores" are lobed, and when the lobes separate (you can see clear glass in between) they are referred to as divided core even though the person making them may not have intend them that way...keeping in mind they were cranking them out pretty quick. There are a couple good marble books that may be a good reference for you. Thats my 2 pence

Agreed with the above, and refreshing to see

It's been packed away for a while so I got it out for a closer look. You're correct, there is a pulp/paper/cardboard backing and the upper face is metal. here is a pic of the bottom

Not tin, actually some type of cardboard (or paper mache) best I can tell.

Welcome to the site. Any specific types you'd like to see (handmade, machinemade, certain types/colors, companies, etc.) can be a click away in the search feature. Or if you're not sure, ask away, and we can assist (as Chad mentioned).

In the original post, top left looks Vitro and the others look Foreign ie: pinchers (or something along those lines)

Took some oddities out for a group shot, (some might not even be Pelts, at least 3 are questionable to me).

Based on that Pic, I agree with Ric

Last one looks newer to me.

I wouldn't normally expect it either but this is what made me ask. could be a rough spot, reflection, or focus issue, who knows.

Is there a pontil on the slag? Pattern does look like it could be handgathered.

Agree on the OP being Alley. At least that's where I kept my shooter sized one (Don't see them around much, at least for me). BerryB's marble is a CAC

Looks like an unusual Petlier to me. Nice!

The clear based look extra cool

I'm kind of wondering if the marble in the original post is is some type of torch work marble. 2nd pic down has me especially thinking that way.

Very interesting. I don't doubt the experts, but would love to see how the pontil (on the other pole) looks on these examples.
