Well, I just found this thread and this forum.  I too have a 2012, 1B funded coin.  I'm considering peeling it.  To be honest I don't know what my real options are that are considered 'safe'-   The coin was given to me at the DEFCON security conference back when these were first being created.  Thoughts?

This coin has the added bonus of having been on stage at DEFCON.
