  A common type of weak-value experiment prepares a single particle in one
state, weakly measures the occupation number of another state, and post-selects
on finding the particle in a third state (a 'click'). Most weak-value
experiments have been done with photons, but the heralded preparation of a
single photon is difficult and slow of rate. Here we show that the weak value
mentioned above can be measured using strong (many-photon) coherent states,
while still needing only a 'click' detector such as an avalanche photodiode.
One simply subtracts the no-click weak value from the click weak-value, and
scales the answer by a simple function of the click probability.
