one dot = one completed scrape run in which this lot was in stock · a ring = listed but sold out · a dash = not listed at all · the last mark is the latest sweep, green when in stock

a roaster's feed can keep a sold-out lot listed indefinitely, so the count above is of sweeps in which it could actually be bought — not of sweeps in which it appeared.
