I'm a noob. I own two Roman coins, only one of which is NGCed. I couldn't yet call myself a numismatist as the primary driver here is an interest in Rome rather than in coins, but here I am with a signature set. The idea of holding an ancient coin in my hand that was spent on who-knows-what by citizens of the Roman empire is just... really cool. Perhaps geek-cool, but I'm good with being a geek.
A completely undisciplined and (at the moment) very very tiny signature set of Roman coins.
