At the Whitman Baltimore Spring Expo, both NGC and PCGS offered special labels celebrating the release of the 2014 National Baseball Hall of Fame commemorative coins at the Expo.
CoinWorld reports:
Among the special labels, both grading services will identify the coins sold by the Mint at its booth at the Whitman Baltimore Coin & Collectibles Expo. The NGC “Opening Day” and PCGS “Baltimore First Pitch” labels will pedigree the coins as having been sold by the Mint at the show March 27.
