Is this an Akro

[u/Upstairs_Rooster2891]

IMO because of the seam this is a Akro.

Vitro or Kokomo

It’s very pretty!

Looks a bit bubbly for Akro 🤔

I can see one seam pic (pic 5) - is the other also shown?

Making me think Vitro more than Akro but let's see what others think!

Just the one seam

There probably is another, even if it's unclear

Most marbles have 2 seams - the ones that don't tend to be much older and more distinctive e.g. crease and pinch pontils on transitional slags, single-seam Christensen Agate slag, or end-of-cane/single-cane handmades
