I dug one much like it..
I'd say Akro Agate for sure. The one I dug was prior to WW1. But you never know with Akros. Add to that everyone and his brother was trying to copy Akro marbles waay back when. It's driving me nuts I hav'nt dug a marble during the last two weeks. Have been working a new site in Boroslavy Canyon just outside my desert ghost town dating circa 1910. Marbles were scarce back then here on the west coast. Hit a buried pocket of old bottles this morning. One being with raised embossed lettering 'FURST McNESS Co' circa 1910. Now back to listening to my CD of Josephine Baker singing Bye Bye Blackbird. Life is good.
