Quote: "Steve27"Sorry, but this appears to be post-mint manipulation. I believe the blank bi-metallic planchet is assembled and then struck. Thus, someone took a normal coin, popped out the center, inverted it, and then placed it back in the rim. That's why the "O" in EURO is on the side opposite the "EUR."Thats a lot of work for a coin that i've just found-I mean i didn't pay for it.Thanks

I have heard a bimetallic coin of my country was for real only 1 piece, with 2 different plated simulating bimetallic.
So I got a coin, put it in a press with a ring on one side and a flat on the other, and the core popped up. Solved question.
Now I joined the parts, and put in the press again and assembled it back; then I noticed I have rotated the core.
Well, I just left it as was, cause if I separate and join again the coin would end seriously damaging it, and kept it as a souvenir. Some time later I realized I had joined it to my spare change and was gone.
I wonder if anyone noticed it and tried to find out what it was about.
