Hi Mike,
Welcome to Oldgas.com
Unmarked reproduction signs are a sensitive hot topic with collectors. Often repro signs are represented by seller as the real thing and they defraud buyers out of their hard-earned money.
Posting a photo of a repro and asking what your real sign is worth is not a good plan. Instead, post pictures of the actual sign you are asking about. Use the Resize Tool that was mentioned in the Welcome email you got from Oldgas.com. Practice image posting in our Testing Area forum.
