That book did well, although there was not a glut of 9.8 enter the market during the high's. Certainly the highlight of the group.
I was reflecting on the other copies, the 9.6 as noted by Sweetlou.
The 9.0 at 9K against a high of $15k
The 8.5 at $7900 against a high of 12K
The 8.0 also at $7900 against a high of $10k
The 7.5 did seem to hold at $6750, still down from the 10K high
Same with the 7.0 held to current prices but $5800 against a high of 9k
The two that I did really notice were the 5.5 and the 5.0. The 5.5 went for $3900 with recent sales in the 5K range and the 5.0 at $3600 with recent sales above 5k.
That was more specifically what I noticed. That book was selling on Instagram and Facebook for higher than the GPA numbers in May-July.
