I fixed them for you, Brian!
I actually think Tom's pretty spot on for most of the guesses...I can't imagine the 2nd print 9.9's going higher than $300 at this time but to be honest I think Tom did a great job at his estimates. We shall see in short time, though!
I think you are a tad low, considering this will be minute auctions and the current 2nd print foils are selling for up to $200 each. Now add in the 9.9 grade, they are sure to go higher than just $50 more than the 9.8.
My actual guesses are
TWDD 1 2nd print gold foil 9.9 - $400-$500
TWDD 1 2nd print red foil 9.9 - $500
TWD 1 5th Ann Sketch 9.9 (there are 18 9.9 and 3 10.0) - $500-$600 - one sold for $350 and another for $700
TWDD 1 Red Foil 9.8 - $400-$500
TWD Negan Lives Red Foil 9.8 $600
