Just looking through this set and found that 2 cards have no gold signature. T. Nikau and Jason Croker are just typed in gold. I guess Dynamic were just a bit too hasty to get things into printing.
I can remember there is few errors in that set gold printing missing someone will know more but there are mistakes in just about every set that comes out.mistakes are not recorded its only knowledge that spread between card collectors there have been in the pass things that have been corrected and reprinted.
