Help identifying a stone

I stumbled on this stone in a pile at an antiques shop today and had an inkling that it just might be a coticule. It was cheap enough that I grabbed it just in case. It is very slick and has a couple of light scratches that I will be able to lap out easily.
It's my first natural stone. Can any of you experienced guys tell me what I might have here? Thank you!

It looks like a coticule,,, or it could be a PHIG impersonating a coticule. :shrug:

It's a very nice looking coticule

Coticule!! Congrats nice piece

Excellent find, looks like a nice natural combo coticule. Enjoy the mellow comfort of a coticule edge!

Thanks guys. I was hoping that's what you would say. Can't wait to try it out.
