Featured Scrimshaw or ivory or bone poker dice

hello all

Here i have a set of 5 poker dice. They are carved and painted, each displaying the 9-ace
of a card deck. Im not sure of their origin, age or material so once again i turn to you guys.

Thanks, Ratsy

 

I dont think mine are the same as the ones on ebay, they all appear to be clear and polished, like bakelite or plastic. Mine are pitted and grained like i would expect ivory to be.

 

Agree with davey, these are bone. And you're right Ratsy, no bakelite.
The pitting is typical of bone, that is where the tiny blood vessels used to be.
Teeth have no blood supply, so ivory has no dark pitting. Ivory has Schreger lines, fairly even lines of a lighter and darker colour, and where it is rounded, the lines intersect, that is Schreger cross-hatching:

Those dots are where veins went through the bone. Definitely bone; As Any Jewelry shows Schreger lines on ivory - yours don't have that.

 

Definitely bone. Not ivory, which is good
