Interesting...the wire rim on the obverse is a good sign it is a genuine strike through, likely from the thin remains of another planchet. Below is likely the type of remains I am referring to..
Very interesting, would this be some sort of employee made error? This seems too unlikely to happen by itself.
Kind of the opposite actually - this is too random to happen intentionally. An employee-made error is going to be something fantastic, and usually artistic and easy to understand. Think of a dime pressed on a nail: completely implausible, but looks really cool and its really easy to see what happened. In the case of the OP, there was some random scrap of metal that got caught in the press. The press goes at incredible speed, beats this thing to crap, it gets caught in another planchet, and that planchet gets impressed with it. This is the sort of perfectly imperfect error that lends itself to authenticity, as opposed to a so-called "error".
Awesome coin. Thanks for posting error coins like this. I looks similar to a Struck Thru Capped Die in its form. That Struck side surface is really funky. 1995 ? I find it interesting the reverse has a very nice and clear strike like a fresh die..
