Hah hah, Top center is the original, No can have.
I think they will look better once they get a patina, you will get more definition, as they darken.
Ray,
I think it a combo of the lighting and the variation in the stamping process.
One of the things I'm going to ask, is to use a heavier stamp say 100 ton instead of a 50 ton. Might help bring some more definition out.
Center bottom is one I wiped with a copper cleaner
