Set a testing appointment before handing over money. We can test many coins and bars in person so you can make a more informed decision.
If you are sorting through an inherited collection, testing can help you understand what appears to be genuine bullion and what may need more investigation.
If you want extra confidence in what you already have, bring your pieces in and we will walk through the readings with you.
Call (617) 564-1630 or use our contact form. Let us know roughly what you are bringing so we can suggest the right testing option.
Bring your coins, bars, or bullion and a valid photo ID. All testing is done in person at our Brockton office.
We use Sigma Metalytics PMV Pro equipment to screen many common counterfeits without harming your pieces. We explain what the readings mean as we go.
Testing is informational. There is no sales pressure. Any private transaction remains between you and the other party and should be completed off property.
Non-destructive Sigma testing means no drilling, no cutting, no filing, and no harsh acid as part of the standard service. In many cases, pieces can even be tested through common holders or sealed packaging.
This service is built for the public — local individuals, families handling estates, collectors, and buyers who want another layer of protection before a private purchase.
