Opinions wanted on Hank Aaron game used bat in auction

[Philadelphia Shamrocks]

I am wondering about this game used Aaron bat that it is currently listed in the Spring auction by Steiner Sports. The $5000 bid price seems a bit low for a 1958 Aaron game used bat from the 1950's. I can't get a good view of the knob, in order to determine if there are any number markings on it. Any thoughts on the quality and value of this item?

Just to get the ball rolling, Malta-Taube give it a 7--so that is pretty good. It is an Adirondack, which might affect the price a little.
