As long as you are happy with the marble and the price you paid, all is good. The issues arise if someone expects others to value the marble the same way they do. In other words, if you buy a typical Conqueror for $10 that is fine, just don't expect to get your money back by selling it to me. 🙂 And fluorescence (reactivity) occurs when light of a shorter invisible wavelength (UV) reacts with a fluorescent (reactive) compound and causes the compound to emit light of a longer visible wavelength - think of the bright green glow that comes from some apparently white glass when you shine UV light on it (the green light emitted by the fluorescent compound in the glass has a longer wavelength than the UV light we used to excite it). UV light that is reflected is essentially the same color as the UV source.

Might be an odd Ravenswood.

The structure is pretty messy but it look mostly foreign to me.

Only for a bit, I'm in Florida for the rest of the week and will only be around occasionally.

Sometimes you can tell by the seams, patch traits, or colors, etc. but there can be so much variation within the different color combos from each maker that sometimes all you can really do is guess. As Ron always says - some just can't be identified with any real accuracy. The red/yellow and red/blue combos are probably the most difficult. From what I see here, only the top right looks like it might be MK - the others look like later Vitro production to me.

Never seen or heard of similar marbles from West Virginia. Is it thought to be contemporary? Any other info about it?

Left looks foreign, maybe Master Glass. The others look mostly Vitro to me, but sort of hard to tell from these pics.

Yes, Vitro.

More than likely Peltier Rainbos.

I'm thinking Akro.

@Chad G. Nice purple color on a couple of those! Here's a wild one with a wandering patch, a good twist and pinched seams too. . . . . . . it's all kinds of weird!

Well, I hope to learn a lot more about these - nice array of colors. Do they have some sort of cut-off mark / pontil?

I hear you . . . it's tough to toss a marble, especially if it's your only example!

Posting some good ones lately, Joe! Red Zebra variants, a beautiful pink patch (why do you think Pelt?), and what appears to be a killer Vitro Tiger Eye variant that could really use a bath! 😀

And I'll bet they are something to behold - you just don't see that many good hybrid Bananas together often!

Lucky, no matter how you look at it! Were they all yellow-banana-based hybrids? What other colors were there? What a great find, Jeff!

Happy Pelt Tuesday!

Some kind of an odd Akro Corkscrew IMO. Really cool one though!

Both nice, Dave, but I really like that red color!

Nice group of Veiligglas, William!

Very nice Heaton, Joe.

Nice Allry Joe - kin of the Lady Tater IMO.

That's a really pretty marble!

@PittsburghMarbles That looks like a great day to me!

The small ones are much harder to find than the larger sizes. I like the size range in the examples you show!
