Mint Akro Agate Silver Oxblood Swirl Marble

This is a excellent looking Silver Oxblood marble by Akro Agate Marble Company. It was likely made more than 70 year ago. It is a great looking swirl in Mint condition. It is a bit over 9/16 inch (measured with calipers). It has the characteristic silver translucent base with white filaments found in the silver oxbloods. There are air bubbles in the glass, and a few tiny air bubble dimples, and a tiny tick, but it has no wear and we grade it mint 9.8.
