A few non-USA marbles here

After the 1930's would be a good start. Probably up to the 1960's based on some of the groups I've seen. No solid evidence, just an estimate.

Better than I can do, looks like fun

I'd lean towards modern based on the views shown, but what does the pole opposite the pontil look like?

Nice, some collectors go wild for these. What's the size?

I know what you mean, there are some that look an awful lot like Pelt construction but are really figure 8 style. Then you get into the Master brushed patch style. Easier to distinguish in a group from UK, Euro, Canada but mixed in a lot of US marbles they can be hard to tell apart

Cool. There are a few specialized collectors here into big Onionskins

An unintentional core probably from contamination or (more likely in this case) chemical reaction in the glass. For some reason oxblood red shows up in aqua glass sometimes so I'd look closer and see if that's the case here

Nice Marbles! Pretty good collection so far. You may have found there are quite a few "nuances" when it comes to marbles that help group by certain names or types. Some collectors will even take it to the point of splitting hairs when it comes to the finest details of grouping marbles. Not to mention the disagreement of certain terms and misinformation published in books over the years... but I think that's part of what makes it all fun! So anyways! Yes your marbles are handmade German, most fit the definition of Onionskin with a couple questionable as Joseph Coat or some other variation. Welcome and good luck

Looks like it from here.

Pretty sure that isn't a Peltier but a new(er) Marble King. That being said, no idea if there is a name associated with it

Some unusual combos there, nice

3/4" and up. Fortunate its been sunny last couple Thursdays!

Smaller one is 3/4"

The last couple marbles look like Rainbos if anything...not even convinced they're Peltier?

The alternating yellow and white core gives it a boost.

Its not a type i collect but if someone showed me that example and said it was a vacor atmosphere? I'd probably say meh and keep walking. ...although the Lutz is kinda neat

Looks handgathered. Not the most spectacular nine and tail pattern. If it was a true orange or peach color would make it a bit more desirable than amber. Condition looks a bit worn

Some type of moonie. Nice size

Pretty sure im seeing some ground/faceted pontils. It's possible they are what he thinks. Pretty big though...and condition + colorlor nudge it towards the 'is it too good to be true' questions...but definitely worth a closer look

Couple onions in the sun

Yep, impact marks. Seems like older quality glass fractures in this pattern. Now I'm curious how the surface looks so smooth in the first set of pics?

Cool marbles. I like the color combo on the last one

to me the OP looks foreign (maybe imperial) and the second marble is CAC

To me it looks like a German Mica marble with some contamination in the glass (which can have the appearance of a different color, etc)
