I believe you'll do better selling them individually than as a group, at least on ebay, particularly if you make sure not to have them all ending at the same time. An auction house might make you more, but if you need the money sooner rather than later, ebay might work better.

I agree that they do not need to be graded, at least the ones with any markings. Buyers should have a good comfort level that these are authentic, and since Colgan's aren't trimmed, the only possible alteration that could concern a buyer is if red color was added to touch up worn edges or creases.
