Late last-year, Mastro had a lot of 17 PSA graded stamps (lot 762). 3 1915 Postaco stamps (Cobb 6, Mack 7 and Alexander 4) and the rest were 1939 Centennial B.B. stamps. In that lot there was a Cobb 8, Wagner 8, Collins 8, Keeler 8, Lajoie 8, Matty 5, etc.
Several months ago, Teletrade had several Centennial's graded by PSA. I have not seen any of those slabbed by SGC.
As you said:

Have you asked the seller that question?
