Frosted Metal Pontil

[Mojo]

22mm 

Frosted Base 

Looks like metallic scratches on the side 

I think the hole on the pole is not a pontill but a flaw ? 

Never seen something like this one before 

Comments welcome 

Help appreciated 

For ID , i lean Vacor

I found a blue one resembling yours called “Frosted Blast” which might just be a blue “Polaris Assorted” or a “Pearly” that was frosted (tumbled I think, maybe another process was used) . 
The Polaris Assorted/Pearly have an iridescent finish which would explain the sparkly fissures in yours. The tumbler did not get all of the iridescence out of the deeper grooves.
Vacor makes/made a number of frosted marbles and It would be OK in my opinion to figure that at least some of them were produced  to stretch the Peso a bit from a bad run of other types of marbles.
Just an opinion here, no facts.
Marble—On!!

No pontil, hole @ the pole is a manufacturing flaw, 100% machine made, agree, Vacor would be my guess on a possible manufacture also.

According to Stephen Barr, Vacor was the only co. to make Frosted Marbles. They made one called " Beluga " that had a light blue base, with white swirls. From the pictures shown,  I don't much white. Sometimes a net bag of Vacors will have some marbles that look quite different from the others.  A sure way to tell a Vacor frosted finish, is that it looks like " Sea Glass ".  Hard to tell for sure if this one has that, from the pictures shown. The size on this one is also kind of off for Vacor. Their players are all around 5/8", and their shooters are around 1". This one is 22mm ( 7/8" )
