Discussion & Detection
Johnson Matthey Gold Bar Value
This counterfeit Johnson-Matthey bar very closely matches the genuine bar dimensions, with the exception of being noticeably thicker than a genuine bar. The raised lettering has a slightly more matte finish on the fake bar, but is still a close match. The most obvious visual indicator is the lack of a serial number (or a laser-etched serial number instead of a stamped serial number). The extra partial logo box on the back of the bar is also a warning to very carefully test the bar, as this partial logo is only present on some older genuine bars, and is not present on the majority of genuine bars on the market today. The fake is very convincing, but easily detected by the Precious Metal Verifier.
