There are two packets of uncirculated coins from the Treasury Department, San Francisco CA. In one packet is a marker stating that packet contains coins minted in Denver and the other states the coins in that packet were minted in Philadelphia. The Denver packet contains the Kennedy Half Dollar. The envelope has some imperfections and smudges but the contents are perfect. - Great gift for your collector friend or family member!! The Kennedy Half is 40% silver. People call this a mint set because it comes from the mint but it is an uncirculated set. The envelope states 1968 U.C. We must collect 6% Pennsylvania Sales and Use Tax at checkout. Thanks for stopping by!
