A puzzler.
My initial assumption would be "smoothed in a rock tumbler" or similar device, but smoothing to this extent would noticeably reduce the mass.
A weak strike - a coin struck only under minimum pressure - would resemble this. This blog site has an example of a weakly struck Australian 5c resembling this. But I'm skeptical, as to the complete lack of lustre on this coin. Plus, some of those dints and scratches seem to go straight through the design remnants, implying they happened after the coin was struck. Surely a weak strike this severe would not actually enter circulation, and circulate for long enough to lose the lustre and get all nicked and dinted, while it looked like this; somebody would have noticed and fished it out before it got to this state.
Would need to confirm the coin matches the weight specifications for the 50 eurocent, and is not significantly lighter.
