Bright green-ish is probably from uranium. Orange could be from manganese. Uranium was used in the 1800's and 1900's ... and then I think there was a time in the mid 1900's when it wasn't available, maybe because of war, and then it was used again in the late 1900's. And I guess it's been used this century, but I don't know. So, no, it usually isn't a clue about the age. Except I think for sulphides (the clear glass marbles with the little white figures in them) ... I think that a faint glow could mean old for those ... and if the faint glow is missing that might mean new. Maybe someone with more sulphide experience can confirm.

Welcome, we'll see what we can do.

Trying to see if the white ones are a swirl structure or two-seamers. In spite of some ambiguity, I'm gonna guess two-seamers. And with that I say they are modern Marble Kings. I can't remember if I have any white modern Marble Kings, but I do have pinks. Small ones. Edit: if the whites are swirly then obviously not MK, but swirly would make them more likely to be Champs.

5/8"?

Hiya Abe!

Wowza, I would totally have it with my Akros. But where is that green coming from? Is that the base? I'm not sure if it is a "mere" Sparkler.

Bump with a Jabo and an Akro.

Ready for April? We could segue into pastels with Jess's last cork there.

I'll have to pull out my copy of Marble Mania. We moved recently and my books are still packed up.

10 a day?! I'm gonna try to get back to two a day. You have cooler stuff than I do though.

Yup, it's hard, but it's addictive! When you look back in a couple of years, you'll smile at what your first guesses for marbles were and how far you've come.

Not slag. Essentially solid color though there are variations in it. If it's a little smaller than normal (closer to 9/16" than to 5/8") it would be called a "game marble". But it's closer to 5/8", isn't it. (Trying to read the tape measure.) The glass texture together with the swirl pattern makes me think of Champion Agate for the first possible maker. With Alley Agate as a fall back choice.

It's a Peltier National Line Rainbo. I think the collector's name for that particular NLR color combo is Superboy.

Looks like a wild one. A big wild one. Congratulations!

Machine-made. The marble-rounding machine which revolutionized the American marble industry was invented around 1900. At that time, marbles were still "hand-gathered". Which meant that globs of molten glass were picked up on a piece of metal and manually dropped onto the mechanical marble rollers for rounding. In the 1920's the molten-glob-producing process was automated. That's when the "gob feeder" was introduced to the process and marbles became entirely machine made.

Here is a thread full of Peltier patches http://marbleconnection.com/topic/21372-pelt-patches/

With your new pix, I confidently say Vitro Tri Lite on the left. A 1930's marble. Still not sure on the right, but it does look vintage. You showed a lot of the white and not so much the yellow. I think it might turn out to be a Peltier patch.

I think it probably is a Vitro Conqueror. A 1940's marble.

Also, I would still like other views of the middle two here.

This last one is a Vitro cage style Cat's Eye. Could be from the 60's through the 80's. If you keep marble hunting, you'll find it's a very common style. A few dollars for the whole group? Or few dollars for an individual? I might pay a few dollars to get the big Marble King Rainbows. Wait for a second opinion.
