Hard to say without comparing the two but I don't think anyone has made repops in the 42" DSP signs. Many oil companies used more than one manufacturer and that could be the only difference in the two. IMO Makers mark / dates usually have no value difference on real signs but that may change as more repops come along. Plus some of the repops are being done with old dates so that just adds to the sickening flavor.

Thanks
