HarryI know that Bushing (not sure about Kinunen) used to work for Mastro two or three years ago, but have been on their own or with SCD since then. I believe that Mastro uses them in the same capacity as American Memorabilia, Leland's, Robert Edward, SportsCards Plus and the others do.
I guess that I look at the memorabilia authentication the same way as card grading and autograph authentication. I take their opinion for what it is - an opinion. They certainly make mistakes, but their opinion can be a first step for my own research if I am interested in an item - I would never buy an item based solely on someone else's opinion.
