Description
A notable variation in the coins in this series is the
artwork surrounding the logo on the backside. It starts
off as a simple circle pattern for the 1 BTC round, but
upgrades to a more prestigious wreath on the 5 BTC
round. The 10 BTC round in turn has a much more
substantial and decorative wreath, implying a higher importance. The 5 BTC coin is notable
for its two-tone plating. It was created in the same year as the Casascius 5 BTC coin.
