1985-D 50C MS67 Certification #81903873, PCGS #6748
From the 1980's to about the year 2000, the Mint was producing about 20-30 million Kennedy Half Dollars from each Mint each year. Therefore, the 1985-D is a common issue since it's mintage is close to 20 million coins struck. It is only scarce in MS67 condition or higher. Anything grading less than MS67 is fairly common and can be purchased very inexpensively.
