I recently had a primal cub born to my king and I just realized today that he had a spontaneous hidden marking, so I checked it under the scrying stone and learned that the marking was Gold Rosette. However, the mark is in slot 14 and is currently unrevealed, as I am not interested in paying for his extra marking slots to make it shown. Here's a link to his page, he's pretty plain aside from the mutation and rosette. In his current state, what would be a good price to ask for him?
