A completely self-contained, battery-powered flashing coin having a series of three visible-spectrum LEDs flashed in sequence when a flash control IC is triggered by a sufficient force, e.g., the force generated upon impact of the coin on one o f its faces or sides from a height of about 50 mm. A cantilever switch contact suspended ov er a stationary contact on a circuit board closes in response to the sufficient force and triggers the IC. The coin is preferably provided with a decorative design and the LED s are preferably arranged within or around the design so as to draw attention thereto during flashing action.
