Pricing jeans question, please help if posssible

I'm going through boxes of stuff from storage, getting things ready to sell. Mostly books, but a few boxes have some clothing, plus lots of collectibles not even moved yet.

I found 5 pair of kid's jeans (3 Levi's, 1 Faded Glory and 1 Wrangler) in pretty good to nearly new shape, size 10-11-12, or waist 25/length 24-1/2. What should I ask for them? Lord only knows where they came from, maybe my mother who did some alterations.
