How do I price my wire bonsai?

We have no idea, as this is a Forum of alive bonsai and not a sculptor's forum.

Well... actually I have seen a wire bonsai on the Noelanders trophy exhibition. It was priced at EUR 3.000,00 I think. It was better looking then yours, but your tree doesn't look bad, really. Can't price it though, this is not an art forum as Clicio said - and I wouldn't buy it.

A thing is only worth as much as a potential buyer is willing to spend, as far as markets are concerned.
I could tell you how I figure out what to charge for my services as a musician, but I'm not sure that would get you what you want..
Are you asking what someone here would be willing to pay? or are you asking how to figure out what your sculpture is worth?
