Is the coin in the middle 1950 pattern 1 Pfennig? [решено]

I found one pfennig that is different in color and quality and it's date is 1950, but has "J" instead of "F" in which was only made according to numista:

is the coin in middle 1950 pfennig pattern or just good normal 1 pfennig?

More likely than not, this is just an ordinary 1950 J pfennig that either did not circulate much or was subject to cleaning at some point (without a detailed, close-up picture it's very difficult to say which).

That being said, there does seem to be a very slight difference in the measurements between the pattern you've linked and the normal, circulation coin. Using a good quality scale and calipers would seem to be the only reliable way to be absolutely certain. If you have access to these, you should be able to get your answer. However, I wouldn't go out and get these just to measure a coin of such low potential value.

Good luck!

Thank you very much! If I ever get a hold of these tools I'll measure it then!

I believe this could be a normal 1950J (thick J in this case) KM#105 1 Pfennig that was used as a classroom experiment where the copper cladding is chemically removed. This was a very common practice so I don't find anything of great mystery here.

Great, in the chest pile of coins he goes then!

​Don't just click on the coin but open it in a new tab and then click on the picture if necessary (and if you see a plus). The result is a decent close-up picture:
