I'm not sure whether or not those are reflective of current market, mostly due to me not pursuing those earliest books in those grades. For example, the TTA #14 listed on MCS is an 8.5 ow/w for $3225 o/bo and I purchased my copy, a 7.5 ow/w 2/19/21 for $316 (not including tax and shipping). Now, that's not the exact same grade, but it IS relatively close and IS comparable. Does it seem to you that the 8.5 should be over ten times as much as the 7.5? Again, people can ask what they want for their books, but like my initial comment indicated ... I'M not very tempted by those prices. Best of luck to whomever owns them!
