[Guardians of the Galaxy - MCU] Why wasn't the collector more interested in Rocket? (Spoilers)

Almost as soon as he sees him (it?) The Collector is interested in Groot, almost in love with him. But he sees Rocket and just ignores him as if he's just a "pet". But... Why? 

I mean, maybe Groot's species is rare in the Galaxy, or maybe he was [Spoiler] interested in a creature that can replicate itself after death [/Spoiler] but... Wouldn't Rocket Racoon be even more rare? Seeing as how he's probably the only talking Racoon in the Galaxy?

Rocket was also manipulated genetically and cybernetically. The Collector is more interested in artifacts of true historical value and creatures which reflect the wide possibilities of random creation. 

Having a crassly tinkered-with creature like Rocket in his home is like bringing a taxidermied jackalope to the Smithsonian.
