What is an OG collector, anyway? I bought a couple dozens of Casascius from Mr. Mike Caldwell himself at end of 2012. Am I an OG? 
Yes :-)

Hmmmmm...I didn't buy a couple dozen but did buy one silver/gilt from Mike himself in 2013...what does that make me? LOL
Is there a time frame and quantity a person must have bought to be labeled an OG?
