Average of confirmed sales; the main valuation baseline.
Lowest active listing; an asking price, not a completed sale.
Reference-price movement; low volume can make it unstable.
More sales reduce the impact of individual transactions.
Sales answer “what is it worth”; listings answer “what does an available copy cost”.
Transaction-based price; use it as the valuation baseline.
