I haven't been watching the 9.8 copies, but I have been watching (and buying) the 9.6 and 9.4 copies, and the book is up in all grades, 9.6, could be had for $300 two months ago, now they sell for $600 or slightly above, and the 9.4 copies during the same time were selling for $150-$200, they are now selling for $225-$275.
I think the 9.8s are catching thier breath, after such a fast upswing in price, the top end copies are always hard to peg, this book reminds me of the pattern BA12 took a year and a half ago.
I wasn't paying attention to BA12 at the time so I'll take your word for it.
yeah, to be more clear on that , it took some time for BA12 in 9.8 to be accepted as a $1000-$1,500 book. Star Wars 1 may follow the same path.
