Verifier

This tool lets you look up the serial numbers on MetalMark bills and Certificates of Authenticity. We’ll see if those serials exist in our database of all serials ever issued and see if they’re legit.

Beyond just confirming we issued them, once we find a match we’ll show you when they were made, how many are a part of the lot, and other details like which edition it belongs to.

For bill serials, these are located on the back of the bill. Though the exact placement varies across designs, it should be labeled “SERIAL” and in a table or grid of other bill information.

For COAs, the serial is shorter and etched on the FIPS-compatible holographic security seal.

The bill serial is usually enough to ensure the bill you have is genuine. For an extra layer of peace of mind, you can also ensure the COA you have is genuine and belongs to the correct lot.
