I’d say it’s real. I looked on worthpoint to find a value for you. It seems in that condition it could be worth as low as 525 or as high as 1000. Some can even go as high as 2k+ depending on condition. I know that’s a broad range but it seems that particular sign is all over the place when it comes to pinning down a value for it.

Here is a snapshot of the worthpoint values of the 4 most recently sold ones.
