Grading raw vintage cards for trade or resale purposes

[Musashi]

First, I generally use PSA's published grading guidelines (spoiler alert: they don't use their own guidelines. If they did, there wouldn't be qualifiers). Second, (assuming these are internet sales) I provide a list of the reasons I feel it earned that grade, with emphasis on any issues that may not be obvious in scans. That way, even if the buyer disagrees with my grade, they still have all the information they need to come to their own conclusion before they purchase.
