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

Its thin, balloon-like body is inflated by horribly toxic gases. It reeks when it is nearby.
