It is rare-ish and is worth a LOT more then the standard card.
$300-$600 would be it's range, BUT finding the right buyer would dictate where it ends up, an auction could see it sell as low as $100-$150 without getting the right buyer involved so keep that in mind.
I'd list it as a BIN-offer $1023 see what you get offered, (you'll get low balled at $50-$100 so expect that) but anything over $300 I'd consider...
I have one too...lol
