I can tell you for a fact the ant coin was never produced...just a render.
And the 5
BTC 2oz coin is real... there is only 1 that was produced... the owner still has it

Was it ever loaded? If so my condolences to the buyer, because those funds were likely stolen with the rest. Although as far as I remember, he only produced loaded LTC coins (which were all subsequently drained).
It's a shame because both of these coins had such a good design and look to them.
