Investment scorecard

Momentum50Measured price direction: the median recorded sale of the last 4 months against the median of 8 to 12 months ago. 50 means flat; small samples are pulled toward 50.

Liquidity52How easily it sells: recorded sales in the last 12 months (300 or more scores 100) and eBay's 90-day sell-through rate.

Scarcity22Demand against supply. For modern pieces, how far the market sits above or below current retail, plus a lift if production has ended. For vintage, how rarely one comes up for sale.

Value entry27Where the latest quarter's median sale sits inside its own 3-year range. Buying near the low scores high; buying at the high scores low.

Condition safety62How safe a typical example is: the age of the design, plus how tightly sale prices cluster (a wide spread means condition and originality swing the price).
