I did a bit of homework on that emerald badge.
it's new-from 1992 and the previous owner has resigned. (ie: is no longer a member of Theta)
just as an fyi for anyone who is considering bidding.. this badge new will run you ~180 to 250 (depending on size) new from the jeweler. so don't go crazy! note: my pricing on my vintage badges is much better!
