I think that they are beautiful pieces, and knowing a back story is all that much better, if selling online make sure that you take quality pics, with possible usages, and if selling at flea-market, I would set up on a table with lamp,and just display it perfectly, and I cant imagine you having a hard time getting $150 for them. That is just solely on design, if some one knows what they are and remind them of back in the day, id say up to $200... but all depends on your audience... Good luck!
