Two types of this coin have been made; all-silver and
with gold rimming. Peercoin is one of the early cryptocurrencies,
with some interesting differences to Bitcoin.
These include no fixed limit on the number of possible
PPC in existence, and it is designed to attain a 1 percent
annual rate of inflation. The hologram for this coin is
notably very small. In 2013, the BTC value of the 10
PPC face value varied between 0.11 BTC and 0.15 BTC.
