1999 Lincoln cent 3 coin bonded set, with the obverse coin being a die cap, and then bonded to 2 coins underneath it for a total of 3 coins and with a total combined weight of 7.5 grams. The die cap and set is very high, and NGC placed the set in a giant oversized holder to allow it to fit. A super neat presentation! The error occurred when the coins were struck multiple times into each other, causing them to bond together. This is a rare error type, especially when there are more than 2 planchets bonded together as is the case with this coin.
