FAQ

How is melt value calculated?
Purity mode:
  1. pure_grams = weight_grams × purity
  2. troy_oz = pure_grams × 0.0321507466
  3. value = troy_oz × spot (spot is $ / oz t)
Junk silver mode uses the equivalent shortcut: value = spot × ASW, where ASW is fine silver troy ounces.
Why does it use troy ounces?
Precious metals are quoted in troy ounces (oz t). Regular ounces and pounds are avoirdupois units. We convert everything to grams, then to troy ounces.
What is ASW (Actual Silver Weight)?
ASW is the amount of fine silver in a coin, expressed in troy ounces. Melt value is spot ($/oz t) × ASW (oz t).
