How this valuation is calculated
Price is regressed on log size, with a quadratic term so the exponent rises with size, plus condition, element, variety and form. Recent sales carry more weight, so the curve tracks the current market. Full details on the methodology page. You can also see the price history or appraise your own specimen.
