Submit a transaction

Report a sale you bought or witnessed.

Every grail Yonex transaction is data the rest of the collector community can't see. eBay shows 90 days. Japan's resale sites are in Japanese. Most deals happen in private forums and Discord servers. If you've recently bought or sold something — or saw a sale that didn't make it onto a public market — tell us. It takes about a minute, and we manually review every submission.

Pick from the dropdown if your racquet is in our catalog, or type free-form for a model we don't yet track.
A direct link to the sold listing if you have one. Helps us verify and keep the record auditable.
Only if you're OK with us reaching out for clarification. Never published, never shared.
By submitting, you confirm this is a real transaction you witnessed or participated in. See our methodology for what happens next.
What happens next
  1. Your submission lands in our review queue. Submissions are not auto-published — every one is human-reviewed first.
  2. We cross-check. If a listing URL is provided, we verify the sale happened and the price matches. If not, we look for corroborating data points before promoting it to "verified."
  3. It joins the price history. Approved submissions get added to the racquet's chart, tagged with the source ("community-submitted, verified" or "anecdotal" depending on how strong the corroboration is).
  4. You get credit if you want it. Leave your email and we'll thank you in the next Market Watch newsletter — anonymously if you prefer.
