- Jewelry estimates use a photographed hallmark and weight in grams; plated marks receive no gold value.
Field notes
The app distinguishes a metal-content estimate from a collector range, which it says is built from recent public sales and listings by condition. If it finds no recent sales, it says so and falls back to melt value. Its jewelry workflow calls for a hallmark photo and weight in grams, and the page explicitly says plated marks receive no gold value; coin variety checks are listed for US coins, but a photo cannot confirm a variety.
