The U.S. Mint will release several issues at the upcoming Whitman Baltimore Expo (March 31 – April 3, 2016), including 2016-W Proof Gold Buffalo $50 coins and 2016-S 13-Coin Clad Proof Sets, and NGC is going to commemorate the occasion with special BALTIMORE SHOW RELEASES designations for eligible coins purchased at the US Mint booth.
NGC reports:
Coins received by NGC on the first day of sales (March 31) at the Baltimore Expo may instead receive NGC’s FIRST DAY OF ISSUE designation. The US Mint purchase receipt is NOT required for this designation but coins must be received by NGC at the Baltimore Show on March 31. Bulk submitters may send coins directly to NGC’s Sarasota, Florida, headquarters for the First day of Issue designation provided the coins arrive by the following business day (April 1). Coins with the First Day of Issue designation will receive a separate listing in the online NGC Census.
