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, 5 on file for this printing.
