A $4 Jordan card sold for $10,350

The autograph was worth 2,435 times the card it was signed on.

The top Michael Jordan card sale on eBay Monday was a 1989-90 Hoops #21 — a common card that has sold 61 times in the last 90 days at a median of $4.25 raw. This one brought $10,350.

Why it matters

The card wasn’t graded. The signature was. In the current Jordan market a certified autograph on ordinary cardboard can be worth three orders of magnitude more than the card underneath it — and that gap, not the card stock, is where most of the money in signed Jordan now sits.

By the numbers

• $10,350 — final sold price, Monday at 8:43 a.m. ET.
• $4.25 — median price of a raw, unsigned 1989-90 Hoops #21 across 61 sales in the trailing 90 days. The middle half landed between $3.25 and $5.99.
• 2,435x — the multiple. Roughly $10,346 of the price is signature and authentication, not card.

Zoom in

Beckett Authentication Services encapsulated the signature and graded it a perfect 10. The slab reads “authentic autograph” — that is an autograph grade, not a card grade, a distinction plenty of listings blur. eBay’s item specifics list the card itself as ungraded, “near mint or better.”

Reality check

One sale is not a market. This is the only signed 1989-90 Hoops #21 in our 90-day window, so $10,350 doesn’t confirm a comp — it sets one. Treat it as a data point, not a valuation.

The big picture

• Monday produced 26 qualifying single-card Jordan sales at $250 or more, totaling $28,681.
• The day’s median sale was $499.99 — identical to the trailing-90-day median. Monday was an ordinary day everywhere except the very top.
• Behind the leader: a 1985 Nike Air Jordan promo at $2,200, a 1996 Topps Holding Court refractor in a PSA 9 at $1,823, and a 1991 Nike/Spike Lee #3 in a PSA 10 at $1,375.

What's next

Watch whether more perfect-10 signatures on common Jordan base cards reach the market — a 2,435x spread is the kind of arbitrage that pulls inventory out of shoeboxes fast. For sellers the lesson is narrower than it looks: the premium attaches to third-party certified signatures. An uncertified autograph on the same card is worth closer to the $4.25.

How we track this

RazMania monitors completed eBay sales daily, filtering out multi-card lots, reprints, and cross-listed items to isolate genuine single-card sales. Prices are final sold prices. Comparable-sale medians are calculated from 61 verified sales over the trailing 90 days. eBay reports sold date, not sold time.
