Doesn't everyone know that there are 10 more St. Laurent's Gold coins found?

Perhaps 7.6 million for that coin might be too exaggerated right now if all 11 coins are to be sold at the same time.
If you want a list of world excessively rare coins, here is some that I can think of right now:
Russia 1825 Konstantine Ruble over half million USD,
Trial China 1982 100 gold yuan minted in platinum, over 100,000USD ...
Perhaps, it might be better to describe what kind of range you are looking for? What country? And perhaps explain in details what exactly you would like to do?
