Joe Dugan Bat ID help

[Lordstan]

Hello all,
I am new to this board, but happened to come across a game used item in my collection. I found this Joe Dugan bat. I am on another forum and posted it there. The consensus is that it is a gamer from the 1928-1930 time frame. This was confirmed by John Taube, Troy Kinunen, and others.
It is 34 1/4 in long and 34oz. It's an H&B bat with a Joe Dugan script signature. I took a bunch of pictures for you all to see.
At this time, I have not decided whether I am going to let it go or not.

I came here to ask for the help of the forum hoping someone might have any further information about the bat or Dugan bats in general, ie seen any sold, ideas about it's value, etc.

Thanks for your assistance,
Mark
