Another that got spun on the rolls - at first glance, I see Ravenswood but it could be something else.

I agree totally, it did not spin correct. Error marbles are very hard if at all possible to identify accurate.

It’s a counter clockwise spin. It’s a 6 not a 9.

If you get a 6 or a 9 spin on a machine made marble. it is not spinning correct.  The hot glob has to spin in all different directions in each marble machine roll groove. If it spins in one direction only you have a 6 or 9 twist and a roll mark. Anyone who has used a three head marble polishing machine knows this well. The marble has to spin in all directions constantly all the time it moves, to stay round in a polishing machine.
