That is a "No Warranty" mark on the bottom. It means AE won't recraft them if you ever need to you or have any structural issues with the shoes you will have to go to an independent cobbler. The $200 deal was really us taking advantage of a very generous MTO policy AE had and shouldn't be a real gauge of the what the Eagle County MTOs were really worth. Still $150 sounds like a lot for used AE's, but they don't look to be in too bad of shape if it is really the shoe you want you won't have a lot of other options.
Thanks for the great response.
Why do shoes get the no warranty mark?
