So I made a texture pack where it re-textures these items (their names aren't changed). This texture pack was originally made for my friend's server.

Netherite ingot -> Money bag
Emerald -> Money
Gold ingot -> Coin
Phantom membrane -> Phone
Steak (or cooked steal) -> Burger
Normal emerald ore -> A block with a yellow dollar sign in the middle

Use it if you want. You're allowed to copy and edit it and you don't need my permission.
Most of the textures I made myself, but for some I used a base image online.
