as to what Orb said about how long it takes to practice and perfect a card trick compared to a coin trick.
since i am mainly a card magician i will answer... it takes anywhere between 3 days to a month maybe more. there are some tricks out there that are super easy and i can perform right away, while other's like Ray Kosby's Raise Rise that take months to learn. (i still haven't perfected that one)
but the same goes for coin magic. for instance, when i first learned Chris Kenner's ThreeFry, it took me about 2 to 3 days to be able to perform in front of an audience and have them be astounded. but other tricks that are more advanced will take longer..
so well my point is that both coin magic and card magic have their difficulties... you can't say that coin magic is necessarily harder unless you compare the difficulty of a coin trick to a card trick with the same difficulty. because there are some easy coin tricks out there and the same goes for card magic.
so i hope that you can kinda see where im going with this.

from the way your talking, i dont believe (coin or card magic) you have much down for audiences. Two to three days to perform three fry?
Most all ungimmicked good coin magic you have to be a complete master at to get any sortof reaction at all.
Card magic for most people: pick a card, any card, and pow! its on top. Not too hard, all you need is to pick two cards up in a death grip and so it around.
or three piles of seven cards... you know the rest.
More advanced card techniques are only going to be used by more advanced magicians, because a normal "card magician" wont put the proper amount of time into practicing it, in this case raise rise.
Raise Rise is NOT hard, but instead incredably knacky. But once you have the ARM move down, youve got the basic effect.
While card routines CAN be based entirely on one move, coin routines cannot. You can only see a french drop or a retention vanish soo many times before you get bored. All the good coin routines use much more than one move AND you have to have perfect technique, whereas you CAN skimp on technique in card magic and still get reasonable good reactions.
And another thing, coin magic is based around PALMING. card magic is based around the PASS. Palming is much harder to get away with, because you donr have much misdirection to palm while they are burning your hands. Your angles are almost NEVER completely covered.
You dont have to master the palm in card magic to be GOOD. But as said before, coin magic is almost entirely dependant on it. The pass and its variations can be reasonably covered, theres always easy substitues for the pass, but not too many in coin magic for the palm.
