You see...I posted it to sell on ebay and deleted my post. I dont see a lot of cents because I am writing to Poland. Dont you think that maybe date was tempered with? If it is real then what is its value?
When i bought it, it was in grading box ms68, but i removed it because it sucked(polish grading company). I paid for it $50 lol.
MS68? Ouch! Looks like a metal detector find. Some nice details on the obverse but the reverse is trashed. Come here next time before you make another purchase.
The coin looks real to me. Before you make purchases in the future, I would definitely recommend using an online site such as PCGS Photograde to get a better idea of the condition of the coin. As for the value, I couldn't provide a well-informed estimate.
The obverse looks decent. But the reverse is all messed up. It's worth more than $1. If this coin was even VG-8 it lists for $49. If the back wasn't messed up you did OK. In VF-20 it retails for $115. IN EF-40 $216, in AU $299. In MS-63 $398. Almost.
Polish Coin Grading Services? Yeah that MS68 grade seems a triffle high. The obverse isn't a canker sore, as it even has some decent liberty action going on. That reverse though looks like it may have done a 4 year stretch at Treblinka. All in all not a good coin, but it does have a bit of character.
It is too bad about the corrosion on the reverse. You could try some good long soaks in distilled water and then olive oil. This sometimes will loosen the stuck deposits on the coin. Good luck. Just don't rub the deposits on the coin they will damage it even further.
