Follow the link that you yourself provided and it shows the auction record for the same MS67 sold at $601 on Ebay. Whether you will realize that price is anybody's guess. Good luck with it.
Citeer: "Kristian Borisov"so that's the most accurate price, right?
it's ebay sale an year ago
The only one sold so somebody was willing to pay good money for it but It is only worth that much to somebody that wants that particular coin. I would imagine that because they were illegally made and there are reportedly only 2 known, somebody else would want yours too. For how much, nobody knows until you try to sell it.
It is possible to find circulated examples for sale, but generally speaking, the market for very high grade coins from this era tends to be pretty good.
Given where you are, you might consider a German auction house.
