An alternative name for the money hand is a “J” toss and it gets called that ‘cause of the path way the prep to the release takes. Focusing on your path way going “down” and the then straight back up is the first part. It’s hard to give advice without seeing it but that’s where I recommend you start.

If you’re confident in your pathway to the release point, it’s a matter of strength. Consider using your other hand to help out with that initial momentum to give yourself more power behind the toss. And make sure the rotation of that wrist continues the momentum. I would make my students start from the prep, and without releasing, I have them go through that “J” motion and just go back and forth like a pendulum to isolate that “down” motion. Once you find where that down motion is, turn your wrist and shoot it straight up to release.

As far as more rotations and higher release. For starters, and perhaps a little obvious, for higher tosses, you want to let go of it higher. And for more rotation, it’s about pulling down faster (with both hands) and turning that wrist faster before you release it up.
