I've used Roth's shell coins across (pp. 62-65) for almost 20 years - David performed this on one of the Tannen's "Stars of Magic" videos. You may want to also check out Paul Gertner's touches to this routine in his "Steel & Silver" yet another great book written and published by Richard). Paul's routine can be found on pages 54-58, and the routine is called "A Familiar Ring".
Another routine that is well within the abilities of the average magician is "The Original Chinese Coin Assembly" (pp. 65-69). I've performed it since 1979 (it was originally published in Apocalypse Vol.1 # 1). It is one of those routines that spectators remember for years.
Also, check out the "Folding Coins Through Table". I've used elements of this routine off an on over the years to nail some complacent magicians that were expecting a standard CTT routine.
In the past, I practiced and performed "The Portable Hole". I haven't been very active is performing for the last 10 years, but in my opinion, this routine is one of the top five routines in coin magic.
Those are some of the standouts for me, but what I have given you is really just the tip of the iceberg.
