-----almost a jinx Chad----I was ready to hit enter when your notification was shown--so here goes--LOL.
Welcome here to The Marble Connection Paulie,
If you are not treated with kindness here just let me/us know---we all will fix it quickly.
If this 2-1/4" orb has no flat spots to anchor it from rolling--I would consider it a Marble, many times orbs come with stands or flattened spots to keep them from rolling on the floor—I think that this one is meant to stand alone as a nice round object.
Many contemporary marble makers make this size. I do not know when a marble or orb becomes an orb vs a marble but yours fits into the marble categories imho.
Thanks for checking in and asking, I think that your Bro will appreciate it regardless.
If you can decipher the signature--we here may suggest a maker.
Marble—On!!
