Silver Dollar Blog - What are the most prominent doubled dies?
First off how did a double die happen?
Each Morgan Silver Dollar needed about seven to ten blows from a working hub. It's interesting to note that the Peace Dollar (1921-1935) was done three to five times.
After every blow the die needed to be annealed. A lot of attention was given, but just the slight misalignment between blows would cause doubling of the die. They were extremely careful with the Morgan that is why you won't find too many double died. As with anything the first time something is done it might take a few tries like the 1878 P as they were being perfected you can find some imperfections in them.
