I have experience on the matter, and Q0 curiosities give the same LP as a Q10 of the same type.
Before however, there were bugs with Q0 curiosities giving negative LP, we know this since Vigilance got a -22mil LP character when he studied a Q0 gold egg. From that incident, I made out to make sure to be able to test Q0 curiosities to see if Jorb/Loftar addressed the issue. Once I had my first Q0 conecow, I put it on a freshly made alt and studied it, 20 minutes later, 50 LP.

As there always is, there is an exception to the rules. This is what happens when Jorb/Loftar want a curiosity which needs to be Q0 since it also acts like a gold nugget.
