Selling a Spellbook

[Thanee]

Well it costs 100 gold to scribe a page of spells, so the value would still be 50 gold by the rules. I was thinking that 0-level spells would be worth 0 gold, but I guess the best argument for them to actually be worth 50 gold is that someone looking to multiclass would be better off to purchase a slightly used book instead of scribing from scratch.

50 gp per page is right, see PHB p. 179.

I can't find where it states that a wizard has every 0th level spell.

In the Wizard class description.

A wizard begins play with a spellbook containing all 0-level wizard spells (except those from her prohibited school or schools, if any; see School Specialization, below) plus three 1st-level spells of your choice. For each point of Intelligence bonus the wizard has, the spellbook holds one additional 1st-level spell of your choice.
