Quick answer
The best-supported top candidate in the supplied market coverage is the Ken Griffey Jr. #40 Tiffany, not an ordinary base-set copy. Sports Illustrated’s collector coverage reports a Tiffany sale of $6,344, while the same source lists a recent PSA 10 sale of $207 for the regular Ken Griffey Jr. #40. Those figures describe particular sales and grades—not a guaranteed value for every copy. Source (accessed 2026-08-24)
There is no single answer that applies to every version of the most expensive 1989 Topps baseball card. A regular issue, a Tiffany issue, an ungraded card, and a high-grade authenticated card are separate markets. Before treating a card as valuable, confirm its card number, issue, condition, and comparable sold listings.
Why rankings differ
Collector lists do not always use the same definition of “most valuable.” One observed ranking places the 1989 Topps #647 Randy Johnson Rookie Card first, while another highlights the much higher reported sale for the Tiffany Griffey. That is not necessarily a contradiction: the lists may be comparing different variants, grades, sale dates, or types of evidence. Source (accessed 2026-08-24) Source (accessed 2026-08-24)
For a practical valuation, start with the exact card in hand rather than a headline ranking. An ordinary, off-center base card should not be priced from a Tiffany result or from a gem-grade auction. Likewise, a seller’s asking price is an offer, while an auction result records what a buyer paid at one point in time. Price-guide figures are estimates, not completed sales.
Leading cards to identify before pricing
| Player and card | Why collectors check it | Important distinction |
|---|---|---|
| Ken Griffey Jr. #40 | Prominent rookie-era collector target; the supplied coverage reports separate regular PSA 10 and Tiffany sale figures. | Do not assume a base copy is Tiffany. |
| Randy Johnson #647 | Listed as a rookie card and the top entry in one observed ranking. | Condition can matter more than the player name on a mass-produced copy. |
| Nolan Ryan #530 | Listed near the top of the same observed ranking. | It is a star card, but not a rookie card. |
| Greg Maddux | Included among notable cards in collector coverage of the set. | Verify the precise issue and grade before comparing sales. |

Regular issue versus Tiffany
This distinction is central to the page’s answer. The reported high Griffey result is specifically identified as a Tiffany version, whereas the reported PSA 10 result is for the regular card. Treat “Tiffany” as a separate identification question before you compare a sale. Source (accessed 2026-08-24)
Use more than a front-image match. Record the card number, compare the front and back against a reliable issue reference, and preserve clear photographs of the corners and surface. If a card may be a Tiffany example, avoid cleaning, trimming, recoloring, or otherwise altering it; alteration can undermine both authenticity review and buyer confidence.
Basic identification sequence
- Read the player name and card number on the card.
- Separate base-set cards from Traded, update-related, promotional, or other similarly dated issues.
- Determine whether the card is regular issue or Tiffany before searching sold results.
- Match the condition and grade of your card to the comparable, rather than using the highest result shown.
- Keep the sale date, platform, grade, and variant with each comparison.
Why condition changes the result
For widely available cards from this era, a star name alone does not create a high price. Buyers pay differently for a worn raw card, a sharp raw card, and a professionally graded example. In the supplied coverage, the regular Randy Johnson #647 is described at about $1 ungraded and $70 or more in PSA 10, illustrating why grade-specific results should not be applied to every copy. Source (accessed 2026-08-24)
Inspect a card under indirect light and at an angle. Check whether the borders are visibly uneven, whether corners show whitening or bends, whether edges are chipped, and whether the surface has scratches, print marks, stains, or wax residue. Also look for creases and signs of trimming or recoloring. A card can look clean in a sleeve yet still fall short of a premium grade.
Use sold prices carefully
When researching, prioritize completed sales for the same player, card number, variant, grading company, and grade. Then compare several results rather than selecting the highest one. A low sale may reflect poor photos, damage, timing, or an uncertain listing; a high sale may reflect exceptional eye appeal or unusually strong bidding. Population data can add context for graded scarcity, but it does not establish what an ungraded card is worth.
There is not enough dated sale evidence in the supplied record to responsibly publish a current price range for every card on this page. That is preferable to turning isolated examples into a misleading price guide. Recheck recent completed sales immediately before buying, grading, insuring, or listing a card.
Should you grade it?
Consider professional grading only after identifying the exact issue and examining the card closely. Grading can make sense when the card appears unusually clean, has strong centering, and has enough likely market value to justify grading, shipping, insurance, and selling costs. It is less compelling when visible defects make a top grade unlikely or when comparable raw copies sell cheaply.

Keep sets, sealed product, and errors separate
A complete set, unopened product, and a claimed error or misprint should be evaluated as separate items from an individual base card. Their condition standards, authentication concerns, buyer pools, and comparable sales may differ. Do not add the estimated values of individual cards and assume that total equals a set’s market value.

A short decision tree
- If the card is Ken Griffey Jr. #40, first determine whether it is regular issue or Tiffany.
- If it is Randy Johnson #647, confirm the rookie-card identification and inspect condition before using any PSA 10 comparison.
- If the card is a star base card with visible wear, search raw completed sales rather than high-grade results.
- If the card appears exceptional, photograph both sides, gather several close grade matches, and calculate grading costs before submitting.
- If it is a set, sealed item, or alleged error, research that category separately.
