0.64” Glows bright under 395 and 365 nm UV wavelengths. My guess is Alley. Almost looks like a game marble until you look close.

Thanks @akroorka what’s the diff between a “classic” and a non-“classic”?

[akroorka]

A jabo ("Jaybo") classic is one that was made by the factory for general sales throughout the world. Just a general marble made for production and sales.
The other Jabo are “Contract runs”. These were made in a special circumstance under the supervision  of some highly qualified marble makers. 
Marble collecting folks would get together—spend some money and get some special marbles out of the effort. These were all limited as to the effort placed and were never made for the worldwide market.
I hope that this helps you out.
Marble—On!!
