die fatigue When I first starting roll searching a few years ago, I thought this type of doubling was something to, until I was educated here and had noticed that it is more common than we think it is, especially the modem coins, they work these dies way to hard. I still struggle with less obvious forms of undesired doubling, if you have a copy of " CherryPickers' Guide" turn to Appendix A and take a look at all the different forms of doubling, you will learn a great deal from it. Or just google search the topic "Other Forms of Doubling" Ken Potter has a cool page dedicated to understanding the different types and how they occur in the minting process.
