Four coins through a table is in my opinion, one of the best effects of all time. I personally have done one version or another for over 35 yrs, and it seems to always garner the best reactions from laymen. I have a stand up and sitdown version, but actually I prefer the sitdown version. I seem to do it most after dinner when I am sitting with a date or with family and friends. It ALWAYS gets a great reaction. My sitdown version is currently taught at my lectures, and is available on DVD on my website. The stand up version is on my 2004 lecture DVD, and in my COINvention lecture notes. However, there is a great selection of routines for this plot, and I am sure any one of them will be killer. The one I used originally for many years was taught to me by Tony Econ back in 1973, and was a combination of Al Baker's routine (BoBo)and Al Goshman's routine (he used to sell it, but I am sure it is found in other sources). Mike Gallo has a great kicker ending, that can be found in (I believe) Encore II, and on one of his DVD's. It can be applied to any coins through the table routine that is done sitting down.
