Both the front and the hologram feature the Primecoin
logo. Primecoin is an early crypto-currency designed
by Sunny King (a pseudonym for an anonymous
individual or group) who also had a hand in Peercoin.
Unlike Bitcoin miners which use vast amounts of
electricity in their quest to ‘win’ hashing contests and thus create new blocks, the goal of
Primecoin’s mining process is to discover long chains of prime numbers which are useful in
a number of mathematical calculations. As a tribute to this, the face value is 11 which is a
prime number.
