I just learned today(!) what a MAD is. Here are three roosevelts and one lincoln penny that have misaligned dies. The dime in the center of the three even has a misaligned die on the front and back! Not a clue of value; not sure if this is a valuable thing or not. But cool nonetheless!
When that happens, at least your gold and silver is still worth something That explosion looks just like what happened in Tianjing... O.O
Misaligned dies like yours are very common and are not considered errors unless the devices are affected.
