Fisk Bat Help

[wmullis]

I know this is not as vintage as most of the items posted on this forum but I could use some education on bats since I know little to nothing about the various different types.

I received this Fisk signed bat as a part of a large auction lot, I am interested in selling it but I am not sure exactly what it is. Some of the terms I seen thrown around are game used, professional model, game model, store model, etc and I wouldn't even begin to know how to tell the difference between them.

A few things make it seem "different" then the other bats I have owned. It is unfinished, it doesn't have a shiny clear coat on the bat, it seem like all natural wood. It has "72" hand written on the knob. From the bit of info I could find this is one way to determine game used bats but I don't see any real evidence of it being used(scuff marks,cracks,etc).

If anybody could help provide a little info on what I might have I would appreciate it. Also, if anybody is willing to throw out a general estimate on what something like this would be worth that would be great.
