I've seen the painted ones bring that much and this is a very old porcelain sign with heavy shelving! I can't say as to a close value but I think it should be worth $250+. Its not perfect but its pretty darn nice!
Biggest thing is whether YOU like it or not! If you like it a lot and its reasonably priced, then buy it. Heck theres no postage involved if its in the neighborhood and thats worth a lot anymore!
If you decide not to buy it then send me an email and I'll try to buy it. I really like it! Good luck---KEVIN
