So I picked up Bobo's book on coin magic a few days ago and everything has been alright, nothing that seems impossible without some muscle memory and practice except one. That would be the thumb palm.

Now it says to place it I need to curl my fingers in and clamp my thumb down. This (at least for me) doesn't work. When I bring a coin, that has been clipped in between my fingers, it hits too low and not where my thumb can grip it. Visual aid: http://i.imgur.com/ReHT2.jpg

Any help on this issue would be great, thanks.

Try starting with the Downs palm. Once it is in the Downs palm position (while fingers still curled in, squeeze the thumb on the coin letting it flatten out and flip into the thumb palm. After a while you will just go straight into the thumb palm.

Another method is just balance the coin on the middle fingertip and go straight to thumb palm, not using the index finger at all.

Hope that helps. Don't give up, it takes a while to develop the dexterity to do some of the sleights. Practice is the only way to learn.

Practice, practice, practice.

Have fun,

I had the same issue when doing it with my non-dominant hand. My dominant hand naturally moved my index finger to the edge of the coin, using my middle finger as a fulcrum, and allowing the edge for clipping to raise up high enough.
