When I saw the thread title I thought it was that guy from 99 who kept asking for people to send him their elite level cards. This is not a comment on this thread, just brought me a little chuckle when thinking about that guy.
When i lost my CO status for a year I pulled out my original Onepass card (red and very flimsy plastic) that has the CO and EA logos on it to present to an agent and that got a chuckle out of her (and I think treated a little nicer.)
