This trick is a bit like a Chop Cup, but with coins. With the Chop Cup you perform a few
sleight-of-hand deceptions involving a small ball, and then just when the spectator thinks she knows
what’s going on, you produce two large balls for an amazing climax. Spare Change has a similar plot:
You do a few sleight-of-hand deceptions involving a dime and penny, and then just when the spectator
things she knows what’s going on, you produce a silver dollar for an amazing climax (the
instructions suggest producing a quarter, but I produce a 1922 Liberty Head silver dollar for
maximum effect). It’s true the two tricks aren’t exactly the same: The Chop Cup has two surprise
productions (the two balls), whereas Spare Change has only one production (the huge silver dollar).
But for an apparently impromptu trick that you can carry in your pocket, Spare Change is just great.
And I suspect it will work for walk-around too, although I haven’t tried it yet for that purpose.
The price is a bargain for such a strong and practical effect.
