These browser-based tools use the reference price you enter. Nothing is uploaded, and no result is presented as a guaranteed dealer payment or appraisal.
Gold, silver, copper, platinum and palladium
Choose a calculator
Use a source you can name, identify the material, then keep the completed calculation when you compare an actual offer.
Coins, flatware or silver
Check silver content
Separate sterling, coin silver and fine silver before applying one documented reference price.
Calculate silver melt value →Wire, pipe or scrap
Sort before you calculate
Material grade changes a copper offer. Classify the item before treating a benchmark as a scrap price.
Use the copper sorting checklist →Value calculators

A contained-metal calculation is a defensible starting point when weight, purity and reference price are known. It cannot identify an item, authenticate a hallmark, measure actual assay, determine gemstones or collectible value, or promise what a particular buyer will pay.
Before selling an intact coin, antique, signed object or historically significant item, investigate its non-metal value before authorizing destructive testing or melting.
