MELT
Re-verify a registered coin
Compare a new photo against the visual fingerprint stored at registration. The hash is tolerant to lighting and rotation but distinguishes different coin instances.
What this is
This document records measurements only. MeltMath does not authenticate or grade coins.
The match percentages and spec-compliance flags are statistical comparisons against published Morgan dollar specifications, not guarantees of authenticity. Re-verification by the recipient is encouraged.
