Had this issue on the 10.5 and now also on the latest build. Only the fine wooden garden lanters and the normal wall lanterns appears on the trade screen. The Fine Wooden Wall Lantern and the normal Wooden Garden Lantern can be sold so far.
That certainly seems to be the case. Just checked the game files and only the Fine Wooden Wall Lantern and Wooden Garden Lantern have data for buying/selling.
I imagine there are quite a few objects that can’t be sold. In some cases, it makes sense. Selling a stone wall? Carrying it away after? That seems a little silly. Obviously there are merchants that turn up with huge piles of rock in their inventory, so it’s not that bad.
Not saying these later cases were definitely intentional on the part of the developers, but it is a possibility.
