Collector / seller read
Mark-to-marketMarket value prefers 90-day median of matched eBay solds; falls back to recent median, last sale, then cost.
Suggested askSlight premium to market value when liquid (≈4–10%). Use as a list guide, not a floor.
Suggested bidDiscount to market value for add-on buys (≈10–15%). Thin tape → wait for better prints.
MatchingStrict title filters: exact slab grade, no autos/lots/parallels, per-card required terms, blocked item IDs.
Refresh cadenceTarget every 3 days via scheduled job or manual refresh. eBay Finding API budget is tracked daily.
