How this report is made
- Source: completed sales on eBay.com in US dollars, from Aug 24, 2026 to Nov 1, 2026; new sales are added every month. Prices are the sale price eBay shows, without shipping.
- Only the item itself: each sale's listing is checked to be exactly this item — accessories, parts, lots, graded copies (where noted) and other models are left out.
- Best Offer sales are excluded: eBay shows the asking price on those, not the price that was accepted.
- Mistakes filtered: sales under 30% or over 300% of an item's median are dropped as likely errors or bundles.
- No user data: built only from public eBay sales — never from what FlipTip users scan.
