About Coin Collection Value Calculator

Retail value is coins times the average catalogue price adjusted for condition, and a dealer's offer deducts their buying margin from that figure. Catalogue values are retail asking prices, so the honest expectation when selling is the wholesale figure rather than the headline total.

Formulas

Retail value

retail = coins x average catalogue value x (1 + condition premium)

Dealer offer
