1 weighing : put 3 on each side (total 6)

if the fake is in there, then you throw out the other 3.

if its not, its in the stack of 3 that wasnâ€™t weighed.

2nd weighing : weigh 1 at a time. Its either there or its the one thats not on the scale.

maybe weighing them all and the one that wieghs less is the counterfit one???
