Lovely gem with multicolor album toning in a rainbow around the periphery of both sides. Mintage of 15,010 issued to commemorate the 300th anniversary of Roger Williams's founding of Providence, Rhode Island. Popular single year issue with P and S mints also struck. CAC approved for quality and eye appeal. CAC is a third party grading service that grades the grading services (PCGS & NGC) and only approves the best coins in holders. CAC coins have been bringing significant premiums at auctions as more and more collectors are demanding the sticker before they buy.
