I also bought from asyn to finish my 5 cent album, some were really nice while others were so-so, yet most were listed MS this or that. With the disclaimer in every description as "grading is our opinion, no guarantee of the same grade from anyone else" kind of clears the way for anything right?
But a more curious thing was each envelope to me actually used OLD unused stamps, including a George VI 5 cent stamp, plus one for International Year of the Child (1979)...
