A Bonded/Mated Pair occurs when a coin was first struck in the normal manner, but instead of completely ejecting from the dies, it flipped over and partially out. A second planchet entered the die area, and the striking of the second planchet bonded it and the first planchet together.
The example, pictured above, sold for $3,737.50 at Heritage Coin Auctions on March 25, 2010.
