Needle Collection Value

What a record collection is worth against what it cost, with the valuation and the cost basis both reduced from the shelf and the gain drawn as the filled space between a value curve and a stepped purchase line. Every copy is then ranked on a diverging bar with what it cost running left of the axis and what it has made running right, and the value is grouped by label and by decade.
