This gold-plated coin is surrounded by the names of
twelve crypto-currencies, with the name of each of
them etched onto the front. There are also twelve dates
on the coin; corresponding to the dates of the ‘Genesis
Block’ of each crypto-currency (This refers to the first
‘mined’ block of coins; essentially the ‘launch’ date).
Though there are 120 of the identically minted coins,
they are sub-divided into twelve distinct categories
of ten each. These categories are the different cryptocurrencies
for which the coin functions as a wallet.
Each coin has a private key under a secure hologram,
with the public key engraved on the coin itself. This
public key (and hidden private key) works only with
the crypto-currency whose name is engraved on the
front of the coin. Exactly 10 of these coins exist for each
of the following crypto-currencies: Bitcoin, Litecoin,
Dogecoin, DNotes, Namecoin, Peercoin, Hyper, Coin2,
ShadowCash, Reddcoin, Clams, and Darkcoin.
