I vaguely recall it did just that in a DC 100 page special. Can someone say if it did and point me to the example?
It happened in Detective Comics #66, Two-Face's first comic. Batman switched his coin with a loaded one that would always land on its edge and Two-Face couldn't act due to his dependence on the coin flip.
The 100 page Spectacular, which you mentioned is The DC 100 Page Spectacular and the story is a reprint of the one in Detective Comics #66.
