looks like an alley agate for sure....alley was operated by lawrence alley and was a prolific marble maker in wv in the late 20s to the late 50s....he was a machinists and made the machines and made millions upon millions of marbles at several locations at factories from the middle ohio river area to the middle central area of west virginia along where u,s. 50 extends from clarksburgh to parkersburgh wv.....many collectors have recently started to collect the wv swirls and some have boomed....i personally know lawrence alleys grandson and hes a member of our marble club....google joes marbles and click on alley agate...
