Check out "Bonsai Classifieds" on FB. If you have not seen this already, it is a new format created by Mark Goodman. So far there has been one auction and another is coming up. It may not be the answer to a better venue but it is worth taking a look. One thing I like very much is you are dealing with people already into the hobby and who knows values.
i am a member there but no where near the money you can fetch on ebay.......yet. I hope that it becomes a go to though. I tried selling some pots last go around and nothing sold. I could have sold them on ebay for what i was asking no problem. Ebay has an abundantly larger audience.
