If you are buying 1943 Liberty Walkers then $10 is an OK deal if they are in VF or maybe even EF condition I think. If you are buying 1920-D Walker that is in EF condition you will pay a lot more. I see
Red Book value of $925 but you what guides say is open to what people are willing to pay now. I have only lower 1920's and valuable teens to fill my Liberty Walker collection. I paid $80 for an EF 1929-D recently. I got a 38-D for $47 but it is in fair condition. I got 1929-S for $60. I feel much more comfortable buying the rare more expensive coins from a dealer I know. If he says it is EF it is EF. Not like
ebay where you are not quite sure and dealers will not actually put true grade on many of the coins. The beat around the bush and lie about condition or are just ignorant.
