My female Rott was bred by her son by accident. Can I sell the pups?

I have a 5-yr. old Female she is half American half German. She has only had 3 litters in those 5 years. Her first litter was with a hunting dog when she got lose from her pen she had 7pups. Two years later I mated her with a full blooded German rottweiler. She gave me 6 but two died at birth. I kept one of her pups from last year, a male. This year she came in heat. I tried to seperate her from her son but I was to late & she gave me 9 pups this year. 5 of the pups are black & 4 are brown. I have never seen a brown rottweiler before. My question is can I still sell these dogs even though the brother is their father or no?

Thanks,
