The first coin produced by Nasty Mining, the coin immortalizes the ‘1NastyF’ vanitygen address used by NastyFans as it’s donation address. It also features a central image of a Bitcoin miner hardware piece. These coins were directly inspired by the ‘MJB Monetary Metals’ 1 gram silver rounds which were released a few months earlier. The reverse rim spells out ‘2013’ in binary code, which is an idea originally implemented by Casascius and later adopted by many manufacturers including Lealana and Cryptolator, among others. There is no numeric year stamp, which is quite unique.
