I have many of R. Paul Wilson’s wonderful effects and regularly use many of them including Challenge
Coin. However with Challenge Coin I alter a small part of his instructions. I tell the spectator he
will make all the decisions but do not say he will do all the actions. Also, in the case of
“rolling” a six, there could be a situation where the spectator misses the prediction before
arriving at it, in which case the prediction on the chip doesn’t quite fit because it seems like a
different bet. So, when a six is rolled, I use a procedure similar to what I use if a five is rolled
– before showing the prediction card I show all the other cards as not matching the prediction and
then reveal the prediction card that does match the prediction. Challenge Coin is a wonderful effect
and I highly recommend it. The metal chip markedly enhances the effect. But if you see it like I do,
the procedure may require a few small changes as described above.
