heys guys what is a good way to go from a three coin effect that uses a forth coin to a trick that uses 4 coins?

I think it would be VERY technically wrong to perform a trick with three coins (such as 3Fly) and then producing the extra coin before moving on to a four coin trick.
If the extra coin *is* the method of the three coin trick, resist the temptation to use the fourth coin for the four coin trick. My advise would be to ditch the extra coin and then cleanly hand out the three coins for examination (destroying the method of the extra coin).
You may then proceed as if the extra coin never existed.
