I see that all the time on Ebay. I don't even like the term, as I think it's a bit too arbitrary, but I don't think half the listings I see are even close to that designation.
I think the one term I've seen on listings for photo's lately that annoy me the most and seems to have become a trend is, "PSA Ready".
LOL, everything that PSA will charge you to slab or authenticate is "PSA Ready".
