How to read these figures
Every number here comes from completed auctions, hammer plus buyer's premium, converted where necessary and restricted to US dollar sales so the comparison is like for like. Condition, completeness and dial variant account for much of the spread within a single reference, so treat the median as market context rather than a valuation of any particular example.
