adsense keyword price 0.05

It seems to show this on all keywords reported "not enough data" for prior months, but still shows 2,000-3.000 searches for the current month. Is the PPC really 0.05 or is that a default because of lack of data?

do not rely on the adwords data - but yes of course that is the best we have.If anything shows no data then it is better to avoid it and move on to some other phrase.
