Machine Doubling is an event that happens during the strike. Some will call it an error, but it is so common I feel it is not something I would call an error.
Hub doubling is caused by a misalignment of the dies/warped hubs/altered hubs that make a doubled set of devices on the die. This is not an error, but a die variety. They will create coins that look like the first one until it is retired. (some allowance for die wear) The people who collect these are called variety collectors.
I view as an error as a one of a kind of error. Wrong planchets, misalignment errors, incorrect strikes and events that create one of a kind coin. (coin struck through a spring/wire/cloth/staples/thread) The bigger the error, the more collectable it is.
Then there are the ones called errors, that are just die wear/die cracks/chips/clashes/struck through grease/die breaks and other events that happen over and over. These I don't give much of a premium for them. Only when they become extreme. (die cracks across the whole die/cuds/extreme clashes and other events that usually create more than one)
That is how I view collectables.
