Please add *2014* on the bottom!
EDIT:
OR maybe (on the outer silver circle) 2014 = in Roman numerals = MMXIV ?
(It can repeat itself say, 5 times, across the circle.)
This is a good idea actually. Would look awesome.
Hmmm or maybe
2014 in binary system?
It would be
11111011110 nice, round number

.
EDIT: Or maybe two of them (
Roman "MMXIV" to symbolize historic aspect of money in a form of a coin as a mean of wealth transfer,
Binary "11111011110" to symbolize future, digital technology and cryptography)?
What do you think?
