About Us

In 2023, the Bullion Authentication Company (BAC) was established by a small group of numismatic experts who realized the demand for collectors to have a service in which vintage and modern bullion is assessed, evaluated, and protected.
​
Our BAC team consists of numismatic and bullion industry leaders and experts who provide impartial authentication and grading.

We are the world's first company dedicated solely to authenticating, grading, encapsulating or certifying, vintage and modern bullion.  

We are located in Casa Grande, Arizona, known for historic gold, silver and copper mining.
