Alley made some of the best single color marbles ever, IMO - it's all about the pattern, and these are great examples.

One thing I have noticed about Vacors is that they often have four ribbon streams which is why some can be easily confused with Peltiers.

New Ole Fashion are the Champions from the late 1980s. Old Fashioned Marbles are old mesh bags with Ravenswood marbles and usually one Paul Bunyan, I think.

That's a nice one. I've seen some patterns that can look sorta close to Pelts, and can understand why some people might confuse them. The differences are much more obvious if you've been collecting for a while though.

It sure looks Akro and there are patch versions of many corks, as far as color goes. I would want that orange to be a lot redder before I called it an Indian Blanket patch though.

But your alarms are working fine and that's the all-important first step!

It's unusually large and being a single color on white makes it a bit more challenging. I am leaning Vacor, maybe Alley. Peltier might be another possibility but I'm not really seeing it.

It's mostly just experience - I've seen a lot of them. Colors, pattern, base glass and size are all clues. They made another that is often mistaken for a K&M. Here's a good pic of both from the WVMCC site. http://westvirginiamarblecollectorsclub.com/Recimages/1351941470.jpg

Nice marble. I like it when the white-based ones get red-washed to pink.

I don't know a lot about them but I think they were made at the Anacortes location. I think there are white and clear based ones. Most I have seen have a single color frit on a white base. But I do think there are some with multicolor frit on clear. I thought they were 5/8" marbles but I am not entirely sure about that. @wvrons probably knows more about them. And I do think you are right about the frit being more "melted in" on the Vitros when compared to Vacors but I don't think the Vitro surfaces are entirely smooth.

How about a feathered Peerless Patch . . .

Nice mibs, Bill! Does that Rebel up front have a special name? And what's that yellow-based one called?

A few more from my stash . . .

A few more . . .

Just some Rainbos . . .

Pointing out misidentified or wrongly graded marbles on Ebay would be a full time job - probably for several people. And I don't think I have ever seen a more valuable marble identified as a less valuable one - like a CAC identified as a Champion. I do think most misidentification is not nefarious though, people who intentionally misidentify marbles are few, at least I hope that's the case. Anyway, the mib in question is 100% Champion NoF.

One of my favorite Rainbo bases - a little different and less common. Nice mib!

I wonder if this one qualifies as a "Dragon"? Nice one, either way.

A few from my peewee stash . . . with too many reflections.

I like it - stuffed to the gills!

That's a great question. I haven't paid too much attention to the Champion wire pulls and I don't have much experience with the Veiligglas ones either, so I'll be interested to hear what people might say.

There is an "Upcoming Marble Show" thread in the main forum that usually gets updated with show info. Bob Block also keeps a pretty good list here: https://www.marblecollecting.com/marble-community/marble-show-calendar/ Where about are you? I might be able to recommend a show or help you find other collectors in your area. Otherwise, just post a "help wanted" topic in the main forum and see what sort of responses you get. Good Luck!

I think Champion is a good call for both of these - size, colors, pattern and ribbon cut-offs can all be clues. If you really want to learn to ID swirls, the easiest way is to get to a show where someone with some knowledge can point out different types of traits to you. There are many WV swirl companies and variables so it's pretty tough subject to teach or learn online. Having said that, pay attention to those traits I listed when you are looking at identified swirls, with some effort, you can probably pick up quite a bit by studying on your own.

No, Champion made some.
