Hey Troy…there are a whole lot of “reasons” that some signs are fake. The older signs often used heavier base metal. The process for making porcelain signs are one color laid over another each fired separately. You can rub your fingers over the levels of enamel referred to as “shelving”. Many fakes don’t have that. Each original sign had a size. Many fakes are produced not true to the original size. I would refer you to some excellent books to read up on the porcelain sign manufacturing process and background on the different signage. I have attached photos of three that are excellent and other members can recommend others. There are a lot of fakes out there and we have all been duped sometime. I hope that helps.
