There is a pink Chase with a crop mark on the back, but I don't think there is a blue Chase with one. Outside of the scrap Chris mentioned (I think there are two of those, Chris can correct me there), the only oddities I have seen are back stamps like the triple-stamped card I have:

Another possibility is to look for varying shades of blue, some are darker/lighter than others. This will be tough bc you will have to trust scans.
Good luck in your hunt, please post anything you find, I would love to see them.
