Here are some routines that really caught me attention that use shells:
Joe Rindfleisch's coin box routine(extreme coin magic)
Homer Liwag's Coin One
Kainoa Harbottle's Shell Shocked Book
NY Coin Guys Coins Across Vol. 1(look into a trick with three coins, roth's shelled coins across, Easy Coins Across, and especially Deja Flew)
Daniel Garcia's Personal Safe

that's a list of the shelled material that really caught my eye off the top of my head, though I don't own a shell so I haven't played with any if them yet.

Mfeld, thanx for the advice, I've tried that, but it's more visual to show the shell and let the coin fall, as in the french drop. They never take they eyes from the shell, so they are convinced that there is only one coin. Try it and then tell me.

Rannie.............. well done... very nice handling.

I almost forgot, be sure to look into nathan kranzo's routines with a shell they look ultra clean and are very visual.

Covert Coins Part 1 from Charlie Justice !! What a nice routine

Thanks Pete!

Best to ya!
