1) First, we need to isolate a control group that has all good coins in it.

Case A) If they weigh the same, neither has the bad coin. weigh group #3 against #1. If #1 and #3 are the same, then #4 is the culprit.
If they are different, #3 is the culprit.

Case B) If they weigh different, weigh group #3 against group #1. If they are different also, then #1 is the culprit.

Take 5 coins from the good coins to be your control group and put the rest of the good coins aside to purchase ice cream and dark chocolate.

2) Whittle down some more.

Break the culprit group into groups of 5.

Put your control group on one side of the scale.
Measure each of the culprit groups against the control group, stopping as soon as you find a group that is different.

Save one coin from the control group and the culprit group that was different.
Put the rest of the coins towards that new dildo you were saving for.

3) Go for the kill.

Take one coin from the control group and measure it, one by one, against the coins
from the new culprit group.

As soon as you find a coin that does not weigh the same, you have found the counterfeit.

Take the control coin and the other good coins and save up for some nice cologne for the boi who just found the counterfeit coin for you...and, please, remember to share the chocolate, ice cream, and dildo with the boi as well.

I knew I was bad with navigation here... I didn't see the other answers first! .... quick, where's my tom-tom?!! LOL

I'd just use my hands and see if there was any discernible difference before spending money on a scale. Then, I would compare it against another coin of the same denomination for a control.

I think people should remember the accuracy of their statements are so easy to check these days with all the modern technology available!

This is a variation of an interview question that I ask. I believe the optimal algorithm is (3) piles of 33 with one coin leftover. Do you have the actual answer?
