There's a bloke on ebay who's selling a un-numbered Ayce Cordy 09 draft sig.
Copied from his listing:
"This card was a replacement card sent to me by Select Australia for another Cordy signature card that was damaged during the packing process. I am told there are only 9 replacement cards available for each player and are only released by Select as direct replacements for damaged cards, making them very unusual."
So if you had a low #'d sig or jersey #'d sig that you were happy with and they sent you back and un-#'d card, would you send it back and ask them to stamp it??
