What You Get

Charter Member Set

Net Zero Coin obverse, depicting a Bull and Bear, stock market metaphors for an up and down market

Limited edition of one thousand Charter Member coin-card sets. A precedent-setting conjoined numismatic (matching serial number on a coin and card). Now in the permanent collection of four museums, including the British Museum, the National Hellenic Museum, the American Numismatic Society, and the American Numismatic Association. Net Zero Coin teaches about the "zero sum game" of the stock market. The mathematical constant, transcendental number Pi is also represented along with a canceling -3.14, rendering the face value exactly zero 

Size: 39 mm (1.534 inch diameter)

Composition: Cooper alloy core, silver bullion mirror proof plating, 24k gold highlights. Reeded edge

Mint: Northwest Territorial Mint (now: Medalcraft Mint, Green Bay, WI) 

Reverse side, Net Zero Coin


Image depicted is of the world's oldest computer, the ancient Antikythera Mechanism (c. 160 BCE). The device was a highly complex 40-geared astronomical calculator which tracked the motions of the five known planets of the era, in addition to solar and lunar eclipses as well as the periodic dates of the ancient Olympic games. Placing a computer on our coin is symbolic of the primary driver of today's economies and the tangential effect on currency spot pricing. A nation's GNP ultimately is reflected in the value of its currency, yet another educational component to Net Zero Coin
