"Gold Coin Question"

Your uncle has a bunch of money in his pocket.

He gives 1/2 of the money in his pocket to your sister.

Then, he gives 1/4 of what's left in his pocket to your brother.

Then, he gives 1/3 of what's left in his pocket to your friend.

Finally, he gives 1/2 of what's left in his pocket to you.

If your uncle has $3 left, how much was in his pocket in the beginning?
