Wayne, for me it's none of the above. I've tried various tricks over the years to visually inspect it, from using a USB microscope, to taking a macro photo and blowing it up, but I'm ever quite sure I'm seeing what I think I'm seeing. I find it impossible to suss it out visually. Instead, I rely on the sound it produces, coupled with a general idea of its previous longevity. It's not exactly scientific, but then again, I don't have rare vinyl records to protect.
