So I have no idea what a stud is worth?

Hello, kind readers.  The TL;DR: of this post is as follows: my name is Han and I'm just a couple of days into this game since it went publicly accessible.  I have a tenuous grasp of the game economy as it stands and general item/wolf worth at best, and I just caved and made a fancy stud for myself today, but while I'd like to list him as available in case someone also likes his looks for breedings' sake, I have no idea what a fair listing even qualifies as? 

The Boy

Could someone with any grasp of fair pricing tell me what a decent price to list is at?  Thank you in advance for the consideration!
