Already mentioned in an earlier thread: Proof-only, mintage 900. Don't know how many survived, or even if you'd call this poor thing a "survivor", but I believe it's the lowest-mintage coin I've owned to date. Still thinking of submitting it, if only for authentication -- I would've sent it to ANACS on the cheap, but they refuse to consider holed coins, unless they've been "repaired". I asked if I could send it in with a cork in the hole, but was politely rebuffed.
