This is PMD right? And what could you use to do that if it is? If not then what happened that caused it? I know it looks to have been washed. A bunch of the Wheaties I found in the trunk look washed. Thanks a lot, Rachel
Think about it what you see in the damage. What are the clues? (1) a cut that shifted out. So the "blades" were not strong enough to maintain it's profile. But it didn't shift like on scissors which come in from the side and flex out in a curve when under stress. (2) on the reverse you see the dig in marks of teeth from a tool. Thus ... think about it. some type of straight nipper type hand cutters (not scissor like). you can go search for specific ones that would fit this exact profile. But it's probably not ceramic nippers as those are very strong (unless they used cheap ones). Look for some artsy nippers that don't have the blade strength and have the teeth on one side. For instance ... here are tile nippers
You're on the right line of thinking ... Just trying to make you think more about when you see something of what could have caused it becz damage is unlimited and mint errors are limited. So the more you can think "unlimited" the better off you'll be recognizing it. Don't limit your thinking to your current "knowledge", search out more when you see something of what could have created it. You're on the right track when you think of pinking scissors, you'll just have to think past fabric applications.
what would really be a neat test, is if you had a round disc cutter for metal, and create your own clipped planchet coins rather than these jewelry design nippers attempt.
