I find smaller coins more difficult certainly - it always seems easier when I switch back to larger coins. This probably means smaller coins are better for harder training.

You can definitely improve your muscles by training. Good practice (for me anyway) seems to be based around
1) Palming a coin for hours at a time (while doing other things obviously)
2) palming stacks of smaller coins (4-8 coins depending on their thickness)
As you develop, you'll probably find that you need to squeeze less to hold the coins in place, this is partly because your hands are getting stronger, and partly because you are more used to the amount of pressure you need to secure a coin.
There's always some compression in the hand while palming, so don't worry not being able to get the hand flat, as long as it looks passably natural. Look at the position of your hands while at rest, and you'll probably see curling of the fingers and thumb in.
