without a picture of the tree (bonsAi) it's impossible to even guess. See if you can post a picture here (on the gallery... see pg top) with a note here for us so we can look at it.

HI. THANKS. I HAVE PUT A PHOTO IN PHOTO GALLERY, GO TO THE CALLENDER ON RIGHT AND LOOK IN DEC 22,

Calendar?? What? There is nothing in the gallery of THIS (bonsai) forum under your name...

OK, I found it. Unfortunately, even though it's large(!), and 'styled', and looks healthy at the moment, it is not really a very good bonsai, and therefore I wouldn't think you could get too much for it relative to others of a similar size, but where are you planning on trying to sell it? That matters too (how knowledgable the customers are, etc.).

Thanks, i had not planned any paticular place to sell it, not knowing a lot about bonsai, i thought if i could get a rough idea of a price, i may give me some idea where to sell,
Thanks

If you can find a local bonsai club, they could probably advise you best about where to sell it locally. OR, you could try e-bay (do you have e-bay there?). It's not a 'bad' tree, but the trunk development isn't good - it should taper, but instead it seems to have gotten lumpy in places higher up - in other words whoever grew it didn't do a very good job - but someone should still be happy to have it for a reasonable amount (100 quid?) or more. Why not find a place that sells bonsai where you live (I don't mean some old guy selling little junipers from the back of his truck, but a dedicated store) and see what others go for?

My advice mirrors Lucy's:
1) compare prices for "similar" trees on e-bay (or other online sources);
2) compare prices locally if at all possible (who knows, you might find a willing buyer right off the bat!).

Good luck!
