The Wallace Sterling Thin mark appears on sterling silver pieces produced by Wallace Silversmiths and likely refers to a specific line or design style characterized by a more streamlined or lightweight form. This mark includes “Wallace” and “Sterling,” confirming the piece is made of genuine sterling silver, with “Thin” potentially indicating a sleeker or more minimalist profile within the Wallace catalog. While not a pattern number, this descriptor helps distinguish the piece from others in Wallace’s extensive range. Collectors use this mark to identify and authenticate items and to understand the stylistic intent of the design. It also provides a helpful reference point for matching or appraising similar pieces.
