How valuable is a dog with no papers?

I crossed my eli with papers into a redboy / alligator bitch with out papers 3 years ago and got papers for the offsprings. Most people want papers some just want to see a performance to them thats worth more then anything a paper say. A dog makes the papers the papers dont make the dog is what i was always told. So without papers could be good or could be b.s. either way you taking a chance. But if it produce it produce nothing more can be said

 

im just wonderin does anyone know of a good producer with no papers i mean grch 35 is the poster boy for the dog makes the papers but he didnt produce worth a piss lol umm wonder why lol i have never heard of a great producing animal that didnt have papers and if so what did they throw that made them so good???
