I'm practicing Gary Kurtz' Triple Spellbound (from his 2nd Magic International Video lecture).It uses a C/S coin and a chinese coin and is very clean and visual.
I want to end the routine with 3 chinese coins and go into Troy Hooser's Chinese Challenge.
I worked out a handling,rather obvious :I palm the 2 chinese at the end ,under the pretext of going into the pocket to get the purse, I do a last standard Spellbound triple change with the chinese palmed in RH. A klink in my right hand."Okay ,I'm caught,I use 3 coins" and I reveal the chinese coins.
Has any one a more subtle idea?

Thanks for the help

Going to the pocket before showing 3 chinese coins might be obvious to the spectators.
If you plan to go into the sucker climax why not hold out 2 chinese coins in RH classic palm, than at least you get credit for not only changing one coin 3 times, but also for being able to "conceal" 3 coins.

I don't know how keen you are on sticking to the spellbound routine with the CCC routine as a follow up.
May I suggest another, more logical routining:
You start with the David Roth Wild coin on Edge...3 silver coins change one by one into 3 chinese coins...now you go for your pocket to get the ribbon, ditch the 3 silver coins and get the extra chinese. Now go into Troy's routine.
Or if you want a more simple method check out Troys work with the flipper and shell and then go into CCC.

Just brainstorming though, succes!
