Thoughts on the value of this Camposportoanum?

This big boy outgrew an 8ft pole, so I chopped it in half and planted them together. Now they are about to outgrow double 6ft moss poles. The leaves have seemed to max out leaf size at just over 12" long and the lower stem branched in two, so there are three stems, each one about 3/4" in diameter. Very healthy and rigorous grower. So rigorous, that I'm thinking about selling it. I can't find any this big for sale, so I'm curious what you guys think it could sell for.
