What is a tamed horse in minecraft value (emeralds)?

Hey I'm creating a Minecraft world where I want to buy and sell a lot, to earn my own money (emeralds) I sell domesticated horses plus saddle, how much can I ask for it

A horse is worth nothing. Emeralds but not either. You get Emeralds through Villager. With your own village and suitable farms, you can do well 1 Stack Emerald blocks per hour.

You create the server?

Well, if an online minecraft world is a server for you then yes 😂😂😂😂😂

Villagers are already out, unfortunately they all died in a small TNT bauble 😂😂😂😂😂😅😅😅😅, but thanks

? There are a few thousand villages per world.
