Where do these prices come from?

From completed sales on eBay.com in US dollars (Mar 25, 2026 – Nov 7, 2026), each checked to be this exact item; Best Offer sales are left out because eBay shows the asking price there. Checked again every few weeks.

How these numbers are made

Source: completed sales on eBay.com in US dollars, Mar 25, 2026 – Nov 7, 2026, without shipping.
Only this exact item: every sale is checked to be this model — no parts, lots, look-alikes or other versions.
Best Offer sales left out: eBay shows the asking price on those, not the price that was paid.
Always fresh: checked again every few weeks; a page whose numbers are older than 45 days is taken down until they are checked again.
No user data: every number is a public eBay sale — never a user, a photo or a scan.
