Coin Dot Pattern Appraisal

Fenton Amethyst Carnival Glass Coin Dot Ruffled Bowl

This is a vintage carnival glass bowl manufactured by the Fenton Art Glass Company, featuring the classic 'Coin Dot' pattern. The piece is constructed from amethyst-colored pressed glass, which has been treated with a metallic salt coating to produce a brilliant iridescence or 'oil slick' effect. This iridescence displays a prismatic range of colors including vivid greens, purples, golds, and blues. The bowl features a distinctively crimped or ruffled undulating rim, which was a signature finishing technique of Fenton's craftsmen. The interior surface is decorated with concentric circles of raised, stippled circular discs (dots), which give the pattern its name. From a condition standpoint, the piece appears well-preserved with high-quality luster; however, there is a visible linear mark or inclusion in the center of the bowl that may be a manufacturing straw mark or a light surface scratch. As an early 20th-century piece, likely dating from the 1910s to the 1920s, it exemplifies the American Art Glass movement's push to make decorative luxury-style items more accessible. The base typically features a collar foot, and the overall weight and clarity of the glass indicate superior early pressing techniques.
