Very nice and Akro IMO.

If it has a UV + green base with black swirls or flames, with no other colors, it’s an Alley Pistachio.

You beat me to it.

Can you see if it lights up under UV light. Has to be ultraviolet positive to be an Alley Pistachio.

Peltier Cerise we’re hand-gathered slags made around 1925, predating the feathered machine slags. They tend to have a poorly defined “9” and are red slags with a single seam. Identification is very difficult and unless they are found in an original box, can be quite challenging to ID. This marble has a well-defined “9” and I will defer to others but I don’t think you have a Cerise , although it is a great marble!

You are correct that MFC did not make red slags. Agree that it would most likely be a hand-gathered Akro.

All look foreign to me. Imperial on the right IMO.

MFC slag IMO

It’s an evolving science. Marblealan was an excellent authority on marbles, but information changes over time. Don’t be discouraged!

Amber is the name they give to brown. Nice MFC Jeremy!

Good to see Kermit gyrating again!!

I would agree with MFC.

This would be a clear slag. MFC and Akro both made clear slags. My money would be on MF Christensen.

Sweet mib!

To me, Akro seams, but colors suggest Vitro.

Tri-lites have a clear base and may have a wispy white matrix. Sorry but not seeing that here.

You’re very welcome!

Sorry, I would not call it a Turkey swirl.

Thank you, Art!

A refreshing Fruit Cocktail for a hot Tuesday!

Supposedly, Mr. Arnold Fielder, of Akro Agate, used potatoes in the batch glass to reduce bubbling in the glass. (Reference: American Machine-Made Marbles by Dean Six, et.al.
