All you can really do is test one or two from your VG seller. It's basically the same thing as buying out of the $1 dollar bins. Whatever money you're willing to risk.
Typically a huge percentage of the dirt can be removed but groove damage, not so much. So that's the gamble of buying any used record on line or one you can hold in your hands. Doesn't even really matter if the rating is visual or audible. It all boils down to is it cleanable without excessive groove damage?Some cracking/popping during playback is from dirt, some can be from damage and some can be from static.
