I have a question about valuing precancel stamps. I always used the PSS database to get a hint of the value of the stamp. But now I got two examples where seller requests a price much higher than value in the PSS database.
Enclosed is a picture of 10c Saginaw type 42, value in database 50c and priced to $25.
Next example Bay City type 841, value in database 20c each and priced to $5 each.
What is a resonable price?
