107 Dollars Space Shuttle Columbia

Not legal tender by any measure — American Art Classics, Ltd. produced these as commemorative novelty items, self-issued and self-printed, with no monetary authority behind them whatsoever. The "107 Dollars" denomination is pure invention, chosen to reference STS-107, the mission designation of Columbia's final flight, which disintegrated during reentry on February 1, 2003. The notes were produced in the same year as the disaster, squarely in the market for memorial keepsakes that followed the loss of all seven crew members.

Collectors should be clear-eyed: this is ephemera, not banknote material in any strict sense.
