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.

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.
