Old Newbury Crafters, often abbreviated as ONC, is a respected American silversmithing company known for its handcrafted sterling silver flatware and hollowware. Founded in 1915 in Newburyport, Massachusetts, ONC is unique for maintaining traditional techniques, with every piece made entirely by hand using hammering and forging methods passed down through generations. ONC silver marks typically include “ONC,” “Sterling,” and sometimes the full name “Old Newbury Crafters.” Their work is celebrated for its exceptional quality, attention to detail, and timeless New England elegance. Unlike mass-produced silverware, ONC pieces are limited in number and cherished for their artisanal heritage. Many of their patterns draw from early American colonial designs, making them both functional and collectible. Identifying ONC silver marks can help you trace the history, craftsmanship, and value of a piece, whether you’re examining a full flatware set or a single serving spoon.
