MELTMATH
Register a coin
Two photos, one weight. ~90 seconds. We hash the images, record the weight against Morgan spec, and emit a public registration URL you can paste in your eBay listing.
Photos: brightly lit, coin centered, fills the frame. Weight: a 0.01g jewelry scale is plenty. We do not authenticate or grade — we record measurements.
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.
