I'm confused. If g does not immediately id the clicks as invalid, you will see stats. This does not mean the ivalid clicks will stay. Please clarify what you mean by invalid.
on a more serious note... no they will not once they are detected. they may appear for a while, but if G decides that they're invalid, you get nothing, if you're lucky. if you're not so lucky, you get an email.......
I clicked on my own ad once by accident, the click showed up straight away but no earning for it.... i emailed google told them what happened, they were happy to hear from me
