Methodology & honest caveats
How these numbers are made, and what they can and cannot tell you.
Sources
Sold prices are individual completed-sale listings observed publicly on eBay for the 90 days ending August 31, 2026, captured August 31, 2026. Every counted listing was title-matched to its exact part number; fuzzy marketplace matches were discarded. Each part page links every underlying listing, so every number here can be checked.
Asking prices are aggregated seller asking prices (low / median / high across covered sellers) observed on a public parts-price aggregator on 25 Aug 2026, shown where coverage exists.
Caveats we want you to know
- The sold-vs-asking spread is not like-for-like. Sold volume skews used and refurbished; asking aggregates include new-surplus and premium-packaging sellers. Part of the spread is condition mix, not negotiation room. That is why every part page also breaks sold prices out by condition band.
- eBay deletes sold listings after roughly 90 days. This snapshot preserves a window that is no longer fully reconstructable from the marketplace itself. Our archive grows from here.
- One marketplace. Broker-to-broker and direct sales are not visible here. eBay skews toward smaller-lot, price-sensitive transactions.
- Zero sold does not mean zero value. For rare legacy parts it usually means the part trades through brokers rather than the open market, or barely trades at all.
- Point-in-time. All figures reflect the stated window and will not update in real time.
