How we compute each section
References on each chart link down here. More notes will land as new sections grow.
1. Price history
- #1.1 · Grade buckets
-
Each seller publishes their own raw condition labels (e.g. "Excellent+", "Like new minus", "Bargain"). Those are normalized to a small bucket set:
mint,excellent,good,fair,poor, andunknown. The "Latest pricing by source" table above shows both the raw label and the normalized bucket so you can audit any individual mapping. - #1.2 · Missing days
- A point is only drawn on a day when a snapshot existed for that (source, grade) pair. Lines connect across gaps so a series with sparse sampling still reads as a single trend, but absence of a point does not mean a stockout: it means we didn't see a listing at that grade that day.
- #1.3 · Color encoding
- Hue carries the source: terracotta = mpb, sage = keh, cobalt = B&H, honey = ebay. Lightness within a hue carries the condition: darker means a better grade (mint and excellent are darkest; poor is lightest). The dashed ink line is launch MSRP, included as a reference even though it isn't a price observation.
