The coin must be placed over the center of gravity or the lemon will tilt, but the center is never right under the top flat part, so the coin will always slide.

Not only that but the weight of the coin will push the lemon down, lower in the water and will change the center of gravity / buoyancy. If CG and CB are offset it'll create a rotational force and you'll end up rich with quarters. This is assuming the lemon isn't perfectly symmetrical if you were to slice it lengthwise.
