What's a blank counterfeit check worth for purposes of federal sentencing?

In U.S. v. Goodson, the Fourth Circuit in a per curiam opinion for a panel of Judges Widener, Williams, and Michael, affirmed the sentence of the appellant who claimed that the trial court over-valued the blank counterfeit checks found in his position, where the trial court valued the 123 blank checks based on an average per check of 74 checks that were filled out.
