100 oz US Assay Office Silver Bar - Random Year

100 oz US Assay Office Silver Bar - Random Year

The 100 oz U.S. Assay Office Silver Bar was originally held and managed by U.S. Assay Offices, part of a historic federal system that tested, verified, and safeguarded precious metals on behalf of the United States government. 

Most examples, made of .999 fine silver, trace their origins to facilities in San Francisco or New York, reinforcing their institutional provenance.

As government assay offices were closed and official inventories were liquidated or redistributed, many of these bars entered the private market. Today, they trade as investment-grade vintage U.S. silver bullion, valued not only for their substantial silver content but also for their connection to America’s bullion history.

Product Details

These bars originate from secondary sources rather than their original mints. Therefore, they may exhibit contact marks or signs of wear, which do not affect the bars' purity or weight.

SD Bullion ensures they are authentic silver bars produced by the US Assay Office containing 100 Troy oz of .999 fine silver.

The Design

Cast bars usually have a more rustic appearance, a rectangular shape, with sharp edges, design elements carved on one side, while the other is blank.

The information engraved refers to the bar’s essential hallmarks, which describe the bar’s weight, metal content, fineness, and issuer. They read: “999+ FINE SILVER 100 TROY OZ,” “CONTAINS SILVER FORMERLY STORED AT THE US ASSAY OFFICE,” “SAN FRANCISCO OR NEW YORK.”
