1999 Lincoln Cent--Two Planchet Bonded Set--MS-66 RD (NGC).5.0 grams. This impressive bonded planchet pair exhibits a full strike both to the obverse and reverse designs. The planchets capped the obverse die, the lower right side relative to the obverse curving up to a maximum depth of 11 mm. Much of the zinc core has been exposed due to the error, although areas that retain the copper plating are bright pinkish-red. Free of post production blemishes with the impressive visual appeal expected of a dramatic major Mint error of this type. Due to its size this piece has not been encapsulated, but it is accompanied by NGC Photo-Certificate #2009397-013 and an accompanying insert with the same number, both of which provide an NGC grade of MS-66 RD.
