Mechanical doubling can produce some very interesting looking coins. There are 1921 Peace dollars that look like they have a doubled profile, but are really machine doubling. "Mechanical doubling" (aka 'machine doubling' or 'shelf doubling') can be virtually identical on a large number of coins. This is because an equipment defect causes the planchet to wobble slightly during striking, and the problem will occur until the coinage press is repaired (or wears through).
