I've been practicing this move for so long and I just can't get it right, I can't get it to look like the ROV pass that the great coin workers have, I know that a lot of those famous coin magicians have been doing coin magic for decades, but it's not like I started practicing a week ago...
Anyone here have a perfect retention pass and can help me improve mine?
I second everyone here -- you're not giving yourself enough credit. I've been on hiatus for the past month, not practicing coin magic; your video was one of the first things I've seen and you definitely fooled my eyes a few times.
Have said that, here are my suggestions, since you asked, taken straight from the master himself, David Roth (I apologize in advance for any repetition, as I have not read this entire post; I'm assuming you're right handed, too):
1) When closing your left fist, keep your fingers straight and together...
...close the hand by pivoting the knuckle joints. Letting the spectator catch a glimpse of the coin through your left hand fingers at first is okay (actually, it adds to the ROV), but, when closing the fist, you must keep the fingers together to block the view of your right (middle and ring) finger tips which make the steal.
2) When "putting" the coin in your left hand, keep your right index finger as motionless as possible...
...in fact, if you can keep your thumb and middle finger motionless, too, as it will add to the illusion. Any major movements of the thumb and index finger/knuckle will draw attention off of the coin. Because of this, it is ideal to make the steal with the tips
of your right middle and ring fingers. Both of these points (right finger motion and the steal) lead to another great tip...
3) Do not
palm the coin immediately after the pass...
...because any extra motion of the right hand will suggest to the spectator that the hand in question is "dirty." Thus, you want to keep the stolen coin in fingertip rest for a few moments while the attention has completely switched hands. One of the hallmarks of a solid ROV fingertip pass is the lack of movement of the dirty hand. Personally, I will either wait until the reveal* to palm the coin, or I will palm under the guise of snapping my (right hand) fingers.
* For the first reveal, I slowly open my left hand with a crumbling motion, as most do; however, I always move my left hand abrubtly away from the right hand after the pass... this rapid motion is a great use of misdirection because the eyes of most people will follow such movement by reflex.
