Below is a sub-wiki that quotes many valuations for the chess piece types; I'm wondering why Kaufman in a book of his published in 2011 apparently changed his valuations to make them nearly identical to what the Dutch world chess champion Euwe gave them (notably single N=B=3.5 and Q=10, though unlike Euwe he has R=5.25 instead of 5.5), which is about what I'd use (I'd put a N at e.g. 3.49, as if to be 'precise', and use Euwe's R=5.5):
