The 1970-D Kennedy Half Dollar has traditionally been considered the key date coin for the series. The coin had a mintage of 2,150,000 due to the fact that it was only released in the government issued 1970 Mint Set and not issued for circulation. Some more recent issues of the series have actually had lower mintages, but this issue continues to retain its allure with collectors.
This year also represents the final circulation strike issue of the series to be minted with silver content. In later years, silver compositions were used for some specially issued collectible uncirculated and proof Kennedy Half Dollars.
