Then, in two separate strikings, the skyline of the Twin Towers and the silhouette of the U.S.S. New York – clad in a total 14 mg .999 pure silver actually recovered from the vaults beneath the ashes of Ground Zero – are inset with a jeweler’s precision, rising up into a 3-dimensional sculpture. The obverse is double dated: 2001-2011. The special reverse features the United States Department of Justice – FBI insignia, along with the mottos: “WE WILL NEVER FORGET” and “JUSTICE WILL PREVAIL.” This unique and unusual piece is minted under exclusive license, and will never be released for circulation.
I guess the FBI insignia is there so we never forget how bad our intelligence services are.
