I think it's from Martin Frederick Christensen & Son Co. (MFC).

The bottom right looks more like a swirl to me - perhaps Ravenswood, or Alley? And I'd guess Akro on the others.

I think the left ones are probably Akro, the top right a newer MK and the bottom right a Vitro.

I like the inherent beauty of marbles, be they glass or otherwise, the learning, history, materials, craftsmanship, classification, hunt, trading and people - not necessarily in that order. 🙂

I don't see any cutoffs/"pontils"?

Too much work, I buy them already shelled. 😊

That is a very nice keepsake collection! And CAC Moonies are dense and granular-looking with a distinct bluish tint so I am thinking Akro for yours.

I think we all see it as a Guinea, Rick - the point is that if only the innards of your marble were in a clear transparent base glass with no surface frit/base color to cloud them then you could easily be looking at a Cobra/Cyclone like the ones Jeff posted - I agree, and with those colors it'd probably be an outstanding marble!

Thanks for the photo and the comments, Jeff - "pretty" is the right description for those marbles!

Who knew looking at marble innards could be both fun and enlightening 🙂 - this is a great example, Rick, thanks for sharing it!

One of my better Heatons for "Sunday Best" this week . . . Horsehair and lots of AV.

That's a cool pinch pontil transitional, Melissa. I agree it looks a bit different than most of the creased pontil Japanese types I am familiar with . . .

That's a very nice gift. The hand on this header cracks me up every time I see it. 😄 I wonder what @Al Oregon knows about this bag. I have definitely seen this Keasbey and Mattison Co. bag before but I've forgotten what I knew about it. lol

Gotta love a good game marble!

Here's my addition . . .

@Dave 13 Way to start the day - the 2nd one is especially nice! @akroorka I really like the pattern on that marble - stuff like that can make a game marble special - weird is good! @Gladys Glad to see you back, I always enjoy the artistic creativity you show in your photos - great marbles too! @Joe2 That's a great marble - tough to find with base glass that color - the mottling is great!

That's a great idea!

I really like a good Vitro "V", especially what I call the "script" style" ones . . .

These Confettis are the most special Vitros I have ever seen - truly extraordinary.

I think the bottom right might be a really messed up foreign Imperial.

I think Jackson.

Welcome to the Marble Connection! By definition, slags are two color marbles that are made with white striping glass in a transparent clear or colored base glass. The variation in colors you see is due to the white being submerged under the colored base glass - the depth and thickness of the submerged white can make it look like different shades of the base color. And FWIW, I do not think your marble is a Christensen Agate - Akro seems more likely.

Unless there is damage to the charging port or the memory itself, it should be pretty straight forward to recover the photos.

There are all kinds of variables in the "UV lights" we use (e.g., the intensity of the light emitted as well as the spectrum of wavelengths emitted), which is why different UV sources can cause different types or intensities of UV reactivity in the same marble.
