There are purses available in which the bottom opens with a squeeze - the same feature which is the opening on some coin pouches.
A piece of fine fishing line attached to a coin, sown half way down inside the purse would make a convincing decoy and would remain inside the purse as the real one was stolen. The dup could even be shook while displaying it inside.
If the coin doesn't really have to appear loose it could simply be glued on one side to the bottom corner.
Or you could do a one handed switch and drop the dup into the purse (or do the switch directly into the purse), if your routine allows it. That way any purse could be used.
