The Challenge Coins are wall-mounted sculptures whose designs are inspired by various military and law-enforcement “challenge coins.” These are awarded to the participants of special operations successfully undertaking aspects of particular missions. These tokens serve as both a competitive incentive for high levels of performance and a manifest form of symbolic currency, marking the acquisition of reputation.

The Challenge Coins are related to the Symbology works in the sense that they explore the visual culture of unseen things. For a longer discussion of challenge coins, see my book From the Archives of Peter Merlin, Aviation Archaeologist.
