lukkyseven - wow that is a very nice gift from your grandfather. what years did he give you? are they all in their own sealed box still? I think each one is under $150 except maybe the 1995W one as there was only around 30,000 minted. But I could be wrong as I have not looked at the going price.
Mine would be a 1909 S Lincoln or a 1912 S Liberty nickel. Maybe an 1857 Large cent or a Carson City Morgan. Then there is the Seated dollar I need for a type set or a Trade dollar. A Texas commemorative half dollar would be nice?
