Monroe 3 point draw bar brackets

I have 2 original Monroe I think brank brackets that go to a 3 point setup and bolt to the draw bar that I am thinking of selling. probably on ebay but I haven't decided yet.

how much should I expect these 2 brackets to sell for? I believe they are pretty hard to find and I saw one just sell on ebay for just under $100 for only one. but another seller had 2 reproductions of these brackets that he wants like $350 for. is that realistic or how much should I expect to sell my original pair for?

 

I would sandblast them first prior to sale but this is what they look like now. they aren't perfect but they are fair to good condition a little extra weld on them could be cleaned up with a grinder and one bracket seems to be missing little bumps on its side that look like they would stop or restrict movement of the "arms" to contain movement or something. may or may not even be an important aspect.
