Authentication Criteria
Weigh on 0.01g precision scale. Compare to official mint specs.
Use calipers to measure. Tolerance usually ±0.1mm.
Most genuine coins (gold, silver, copper) are non-magnetic.
Count reeds and compare. Edge lettering should be consistent.
Examine under 10x magnification. Seam lines indicate cast copy.
Acid test, specific gravity, or XRF analysis.
Artificial patina often looks even/uniform. Natural patina is irregular.
Compare to reference images. Counterfeits often have soft details.
