If you don't know the difference between them it's going to be difficult to know if you have a DD based on class 1, 2, 3 .... or class 8.
Those classes are the Methods of how the doubled die was created and not the different DD types in those Classes. For instance with Class 8 there are .. who knows .. hundreds of various different DD cents types out there.
Where as Mechanical Doubling, Ejection Doubling, Die deterioration Doubling etc are just manufacturing defects where the "low" quality is acceptable and allowed as the main reason for coinage is for commerce and the coins have to be visually identifiable as money. High quality coins such as Proofs, etc are minted for their "high" quality specifically for collectors.
