100 oz U.S. Assay Office Silver Bar .999+ Fine

100 oz U.S. Assay Office Silver Bar .999+ Fine

The 100 oz U.S. Assay Office Silver Bar .999+ Fine is one of the most recognizable and sought-after vintage silver bullion products in the precious metals market. Produced by the historic U.S. Assay Office, these substantial silver bars contain 100 troy ounces of .999+ fine silver. Both investors and collectors prize them for their trusted origin, vintage appeal, and enduring reputation.

Originally produced during a pivotal era in the American bullion industry, U.S. Assay Office silver bars have become increasingly popular among collectors of vintage bullion. Their connection to one of the most respected names in precious metals refining adds historical significance beyond their intrinsic silver value.

This listing may include either cast (poured) or extruded U.S. Assay Office silver bars, depending on available inventory. Both varieties contain the same silver content and purity, though their appearance and manufacturing characteristics differ, offering collectors a unique opportunity to acquire a piece of bullion history.

The U.S. Assay Office played an important role in refining and storing precious metals in the United States. Vintage bars bearing the U.S. Assay Office hallmark remain highly desirable due to their limited availability and historic significance. The hallmark is prominently displayed at the center of the bar, surrounded by decorative stars and crescent motifs. The industrial finish, surface texture, and vintage character reflect decades of storage and handling, qualities often appreciated by collectors of classic bullion.

Cast and Extruded Varieties

Depending on current inventory, customers may receive either a cast (poured) or extruded U.S. Assay Office silver bar.

Cast bars are produced by pouring molten silver into molds, resulting in a distinctive handcrafted appearance with natural cooling lines, surface variations, and unique character.

Extruded bars are manufactured using a different production process that creates a more uniform shape and finish while maintaining the same silver purity and weight.

Bar Features:

• Made from .999+ fine silver with a weight of 100 troy oz

• Manufacturer: U.S. Assay Office
