Yes, this is the greatest thing about bonsai. The work of generations is accumulated in one little tree. Some of the trees I'm working on, have already passed two generations of bonsai artists, before they got to me. After working on them for a decade and a half(or more) myself, it's hard to let them go without any assurance that they will be well cared for. The dillemma is that people who would pay a good price for such a multi-generational tree, may not have the necessary skill. For them, $500 is nothing. On the other hand, for people who you know that they will be thrilled to own such a tree, $500 is not an affordable option. I tend to believe that I'd rather sell the tree for half the price (and basically get back my money that I paid for it, as raw material) if I know that the tree will continue to thrive in the future.
Trees such as these with that kind of provenence, if of that caliber, should be donated to the Huntington for future viewers with your name among those before you. Of course there is always the danger of your tree being worth mayby 85.00 and it will be sold off for 75.00 to keep up the good trees.....
