Let me show you an example to help you understand what you have:
Note on this example how after the normal strike, the die bounced a bit, moved sideways and altered the top half of these devices. The same thing happened on your coin, but touched even higher on the devices. perhaps the upper 1/4 of the tops of the devices was affected. It does look interesting, but how I tell that is what it is? Note the affected areas are flat. (devices no longer contoured) Same color. (Because they are now flat and not rounded) It was so high a bounce it almost didn't happen. It any higher I would have called this ejection doubling. (MD that happens on the tops of devices shimming them slightly) Then they would look like this:
These happen to hit something on the way out of the chamber. But there is no premium for your coin, but you may want to keep it as it is the first I've seen like that.
