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 October 17, 2026, captured October 17, 2026. Every counted listing was title-matched to its part number (manufacturer suffixes and series letters such as -GP or /B are allowed); listings of a different part, accessories, repair-service listings, and bundles with other parts or modules 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.
- Best-offer sales with hidden prices are left out. When eBay shows a sale as best-offer-accepted without showing the price, the price is not public, so that sale is excluded from every count and median here. Counts can therefore understate how many sales actually happened, and because best-offer sales often close below the listed price, published medians may sit above what buyers actually paid.
- 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.
