Authenticate 1 oz gold coins by diameter, thickness, and weight
A precision tool that tests 1 oz bullion coins for diameter, thickness, and weight. No batteries, no guesswork, always reliable.
How it works
Seat the coin in its gauge. An authentic coin fits the exact cutout for its type, often snugly.
Slide the coin through the slot. Too thick or too thin, and it fails.
Rest it on the fulcrum. Density-controlled polymer is perfectly balanced for an accurate reading.

Haven’t used it to determine if a coin is fake but just had one returned from grading as counterfeit so people it does happen. I would invest in this if you are a golf or silver collector!
