Value of Americana Series Vanishing Classics coin collection?

From what I've found, this collection contains one each of a 1943 steel Lincoln cent, a buffalo nickel, a Mercury dime, a Standing Liberty quarter, and a Walking Liberty half dollar. The sets appear to contain common dates in circulated condition for the nickel through half dollar. The cent is worth around 25 cents, the nickel maybe 50 cents, the dime a little under $2, the quarter at about $5, and the half dollar for $8 (Liberty quarters generally have a slight premium above melt value due to their relatively low mintages). Add it all up and the set is worth about $16.
