Bought the 50th anniversary Kennedy half dollar uncirculated coin set today. To me the profile of Kennedy's bust on the Denver mint looked bigger than the Philadelphia mint bust. I started looking and noticed there was a valley between the legs of the "R" in the word "LIBERTY" on the Denver coin. I don't know if I have anything other than the coin but wanted some opinions, DDO or die chip or nothing? I am posting pictures of the other coin for comparison purposes. I also put arrows in the area that I think shows a valley. I'm sorry for the quality of the pictures, it's the best I can do. Thank you!
