I was looking in the Guide for chips I am missing and noticed Greg only lists one of these (one has a UV mark). It turns out I have three examples of this chip, one has no UV, one has a bright UV, and one has a weak UV.
Question: when the UV is being added do they run out of UV marker when making the chips?
Do you care if the chips you collect have a UV mark if the chips look the same under day light?
