If you crave to conjure this confounding coin conundrum, you need the Coin Cidence PDF.
 
Ben Harris:  "Tom Frame's “Coin Cidence” qualifies as a true gem.  It's cunning, subtle and engaging.  I love the Schrodinger Swindle!"
 
Curtis Kam: “I had a chance to perform “Coin Cidence.”  It’s clever, and your method for identifying the coins is simple and brilliant.”  
 
Mike Powers: “Tom Frame’s “Coin Cidence” is a baffler.  It’s not only fun to perform, but it also offers new techniques that will inspire your creativity, as it did mine.”  
 
Mr. Powers liked it enough to schedule a meeting with members of his brain-trust, Craig Alan and Anthony Vinson, to further explore its possibilities.  Their resultant effect, which I dubbed “Two-Fisted Coin Cidence” is a thing of beauty.  I am humbled and delighted to include it in this PDF.   
 
 
The performer and a participant shake a half dollar and an English penny in their hands.  They put their hands beneath the table, take one coin in each hand, close their hands into fists and place them on the table.
 
They open their hands and discover that they are both holding the same coins, in the same orientations in the same hands.
 
 
The 15-page PDF coincidentally includes 15 photographs.
