Was at a flea market last Summer where an antiques dealer was trying to sell (with no luck), station signs marked: SAXONVILLE, BONDSVILLE, DOVER, HOPKINTON, WEST MIDDLETON and some others I didn't recognize. He got no bites @ $300 per sign.
The signs were at the Rietta Ranch flea market, where it's difficult to get serious prices for anything antique, from my experience trying to sell things there. Chances are if the signs were sold @ Brimfield or one of the major train shows, they would have been grabbed in a flash.
