19th Century US Covers

It kind of flabbergasts me when I look at indvidual 19th century covers on the internet..the prices asked...when I go to a show there is always one or two dealers with boxes full of them you can pick from at no more than a buck apiece..possibly the internet sellers are hoping that someone looking thinks the 19th century covers are rare..or worse yet have no access to stamp shows. I will be diving at the White Plains either Friday or Saturday...gives me an excuse to bump into the G man !!

G'Day Phil yes please if you can find 19th century covers with higher denominations above 10 cents Columbians excluded that would be great so please email me regards Harry
