i have
inherited my grandfathers stamp collection---accumulation one dealer told me I should call it---and I am in the process of sorting, organizing, valuing, and possibly selling. I am not sure about the centering on my $4 and $5 columbians where they land on the grading scale and I am hoping to get some opinions here. Also I am wondering what all can you tell me about the gum condition from looking at a scan...anything?
