Yes, it has a distinct Jabo Classic appearance.

There are some Asian marbles surfacing which highly resemble the Mexican. 

21 mm is .83 inches.   At that size, yes, the likely options are Jabo or Mexico for modern, Alley for vintage.  

With the glossiness, modern does seem likely.  But I'm not sure which direction to go from there.   Possibly leaning Jabo but really not sure.
 

I hear your assurance that it is clay.  I still can't see that though.  The high shine doesn't go with clay in my mind.

It looks mineral.  



Normal clays are worth very little even in mint condition.   

Typically we will want to see views of seams.  You're showing one in this image.   Getting clear looks at both seams of a two-seam marble can be helpful in making ID's. 


 

Lighter?

Could be normal clay, but it's larger than usual for basic "commie" ... the most common clay marbles.  

The shininess is also unusual for an older clay marble.  But that could mean little to no play wear, I suppose.  If it is common clay, then don't wash it.  I've had the colors come off when I washed clays.  

Yes to Vacor.   

A Peltier Rainbo for the general style.

A Peltier Muddy for the particular color combination that you have here with that orange translucence inside.

I agree with your reservations -- not a Bennington.  

Is your sense that it's a lighter or heavier marble?

From the pictures I'm leaning toward a newer, more dense clay than a Bennington would have.

Still going with CAC ... or some other old slag ... on the baby blue.

The "red" now looks more "amber" ... and it looks vintage.  Whatever it is.

Steph maybe you can show closer look at yellow and green ones! would love to see thank you

Heading out now for an appointment, and I suck at follow-ups, but a note is made.  It might happen.

What's an OP?🥴

Original Post  ... the start of the thread.

Or Original Poster in some contexts.  

Two seams.  One pair of white ribbons. 

Could be Peltier.  I'm not sure but am hopeful for you.

That's a neat bit of history.  

Disappointing developments but you can display it all together in a Riker case.  Still a nice thing to have in your collection.  

beautiful

Marbles are likely Vacor.   It would be cool to have that header.    Would be interesting to eventually learn if there is a date on the header, but would be nice to have it no matter the year.

(Don't take it off the bag or bend it ... just maybe somehow give us a closer peek.  )

Sherry, could we get close-ups of that header?

Thank you so much for your help with these.. 

Yes, that’s my signature  I’m an artist.. as a another hobby anyway. The image is one of my little creations..

I'm missing something.  I'm referring to the sharp shooter bag header.   That looks "real" and interesting to me.  

Your avatar IS beautiful if that's what you thought I meant.  

William, is yours metal?

There are some nice precision calipers which don't have metal.  I haven't researched or invested.  I actually do use metal, but I worry about damaging the marble.

Maybe Anacortes Vitro?

Agree.  Not U.S.

Maybe Vacor.   But there's a new crop of Asians which look awfully close to Vacor so all I feel safe saying is not U.S. 

Alley seems a good thought on the middle.
