Work out stamp collection value instantly with clear inputs, formula shown and shareable results.
Catalogue total is stamps times the average catalogue value, and market value applies a realisation percentage that reflects what collections actually sell for. Common material typically realises 10 to 25 percent of catalogue, so a large accumulation is worth far less than its catalogue total suggests.
Market value
market = stamps x average catalogue value x realisation percentage
market = stamps x average catalogue value x realisation percentage. Catalogue total is stamps times the average catalogue value, and market value applies a realisation percentage that reflects what collections actually sell for.
Common material typically realises 10 to 25 percent of catalogue, so a large accumulation is worth far less than its catalogue total suggests.
Enter number of stamps, average catalogue value per stamp, typical realisation against catalogue. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
