Creature values

Im trying to sell some of my creatures i dont need in the trade realm but i cant find a good source that tells me genuine up to date values for each of my creatures. This is my first time even using the trade realm, ive never traded before, but i thought itd be a waste to keep a bunch of creatures i no longer need and not sell them for shooms.

If anyone has any methods of finding accurate values for creatures please share, i dont even play the game enough to know whats popular and what isnt😭😭
