This is a set of three vintage cups produced by Wilton Armetale in Columbia, Pennsylvania, marked with the RWP (Ralph Wilton Pewter) touchmark. The cups are likely made from "Armetale" or "statesmetal", an aluminum-based alloy designed to look like pewter. They feature a classic, simple "Jefferson Cup" design, typically measuring about 2 1/2 inches tall and 2 7/8 inches in diameter at the rim. The finish is a matte, aged metal, which is a common characteristic of this type of metalware. These items are durable and often used for serving cold beverages or as decorative items. Condition is used, with a natural aged patina and minor surface wear consistent with age.
