Hi,
in my opinion it is a great bar when someone is looking for a small bar (I guess it is 6", isn't it?). I have always liked the design. The strength is beyond doubt. In my opinion the value depends on if it is uncut or not and how good the paint/chrome is.
If you do not need the money I would recommend to put in on the wall in your living room. It is a true classic and a part of flatland history. Think about Rich...
I have a Graveyard OG and would not sell it, even though I prefer a higher handlebar today.
