Alley Agate

Alley Agate Company operated out of Sistersville, West Virginia, and produced a broad range of machine-made marbles across its years of operation. The company is well regarded for colorful swirl designs in both translucent and opaque glass types that display well and hold their own alongside output from better-known West Virginia manufacturers.

Alley marbles are sometimes overlooked relative to other American makers, which works in the collector's favor. Strong examples with good color and clean surfaces remain findable, and the category rewards collectors willing to look carefully at condition and pattern quality. Every marble here has been individually selected, inspected, and graded.
