50 pfennig 1950 without mintmark?

[pk2017]

Can anybody tell me what is it? Weak strike? Intensive wear? Obliteration of mintmark for fraud? Coin itself is absolutely genuine and was bought as a part of large heap of small coins of German Federal Republic. Sorry for English.

Hello PK,

all your ideas are possible. There are coins known with weak strike in that year, there are manipulated coins known wich should be sold as misstrikes...

I´m not shure, but in my eyes it is manipulated: the place of the mint mark is brighter than the rest and the scratches are deeper in this space...
