I would like to trade Walking Liberty halves and Mercury dimes that I have duplicates of for Walking Liberty halves and Mercury dimes that I lack. I need the following Walking Liberty halves (1938D, 1939, 1946, 1946D, 1947, and 1947D) and Mercury dimes (1921, 1936S, 1938). I also don't have the 1916D dimes, but I won't worry about it. At one time I had duplicates of almost all the others, but many have sold. If you're interested e-mail/respond to me.
