What does the “KISWIN1” mark mean?

The Stieff Winslow Sterling (1850) pattern is among the earliest and most distinguished examples of American neoclassical silver design. Crafted in solid sterling silver by the Stieff Company of Baltimore, this pattern reflects the mid-19th-century aesthetic of refined symmetry, graceful contouring, and understated ornamentation. The design features delicate scrolls and balanced edgework, embodying both the craftsmanship and formality of early American silversmithing traditions. The monogrammed editions were often hand-engraved for prominent families, turning each set into a personal heirloom. First introduced in 1850 and continuing in various reproductions and adaptations through 2008, Winslow exemplifies Stieff’s long-standing dedication to heritage craftsmanship and classical beauty. The Winslow Sterling pattern remains a symbol of timeless American elegance, merging 19th-century neoclassical grace with the enduring quality and artistry that defined Stieff’s silversmithing legacy.
