Need help pricing 3 male pups

I'm a new player and this is my first litter of pups that I'm selling so I need a little help figuring out a good price to list these 3 guys at.

Pup 1 (T1 Khaki male)

Pup 2 (T1 Marengo male)

Pup 3 (T1 Marengo male)

The one with a marking - maybe 20-30 sc/1 gc? The others only like 15-20 sc since they have no markings. You might need to sell them for even lower tho: tier 1 pups with no/few markings, especially males, are not really super valuable I'm afraid. And Khaki is not always the most favored base also btw, so he might need to go for even cheaper. ^^
