The odds of finding the real deal depends on how many counterfeits are out there. If there really were 10 minted & 5 are unaccounted for, the odds of your find being genuine are actually pretty good. Explanation: how many counterfeits could there be out there? Who in their right mind would think they could make one that would fool someone who would pay $1M for it? So let's assume here are 100 counterfeits out there, and 5 genuine (on top of the genuine coins accounted for). Your odds would be 1 in 5 (20%). that's pretty good odds!
Realistically tho... You'll never find one.
