All 2 printings of this card
PSA prices each printing separately and they differ by more than an order of magnitude. Make sure you are looking at the right one.
Value by grade
The rate column is how often a submitted copy earns that grade. A low PSA 10 rate is what makes a gem copy expensive.

eBay sales open eBay's sold listings for this card and grade. Auction house sales are shown for the record and are not linked.
How these figures are calculated
- Method
- Trimmed median of PSA-recorded sold prices, never a mean.
- Window
- The last 30 days, widening to 90 then 180 days only until at least 5 sales are found. Cards from sets released through 2007 may widen once more, to 12 months, because they trade a few times a year. Older sales never set a current price.
- Floor
- Fewer than 3 sales after trimming and no figure is published, rather than printing a guess.
- Sources
- PSA auction price records, 272 on file for this printing.
