shelf cred 

Respect and trust for a person's opinions and recommendations about reading material based on the caliber of their own chosen reading material; can be based on preference of genre, but typically earned by reading stories and novels of subtance.

I'm shocked that Amanda read the Twilight saga. She has a lot of shelf cred with me. Well...she used to anyway."

Whenever I feel like a reading a romantic novel, I ask Maggie. She's got the most shelf cred when it comes to love stories.

self cred 

The internal equivalent of street cred. Believing in your own worth and value. A quote that doesn't use the word but expresses the concept is James Baldwin's "It took many years of vomiting up all the filth I'd been taught about myself, and half-believed, before I was able to walk on the earth as though I had a right to be here."

I was always quiet because I had no self cred.
I didn't believe in myself, I had no self cred.
