Check out what people said about it here:

An individual said, “0.625. Assuming that the fake coin has heads on both sides."

A second said, "75%. There are six sides you could have gotten in the first flip, four of which are heads. Since you have heads, and two of the four heads are on the trick coin, there’s a 50% chance you got the trick coin. If it’s a trick coin, there’s 100% odds of getting heads again, and if it’s not, there’s 50% odds of getting heads again. Since each scenario is equally likely, we average them and get 75% odds of heads on the second flip."

A third added, "5/6. 2/3 of the time it will be from the all-heads coin, and 1/3 of the time you will still have a 50% chance of getting heads."
