Perhaps the doctor meant for these to be lost and not found, or that the daleks was afraid of them?

I think Doctor Who was finding its feet in the Hartnell era and it was Troughton who really first defined the character to what he became later.

In the Hartnell era, the Doctor was a grandfather I think, looked old (although Hartnell was much younger than he appeared, thanks to the war etc) and seems to have been human.
