GREAT BRITAIN. Mint Error -- Missing Center Insert -- 2 Pounds, 2005. Llantrisant Mint. Elizabeth II. NGC MS-64.S-K18; KM-1052. Weight: 5.9 gms. About as dramatic as any mint error, this stunning piece is quite obviously missing the central copper-nickel core meant to honor the 400th anniversary of the Gunpowder Plot. The tiny bit of the coin that remains is well struck and lustrous, though the real appeal is in what is missing, rather than present on this piece. Certain to be a lot much contested for.
