Building a Magic System for Divine Coins of Domminna.

I see Copper, Silver, and Gold Coins.

What do they do?

I could also add Bronze, Steel, Iron, and Platinum Coins.

The Coin Mint is inside the Planet Gnorrum, deep underground.

These are considered "Raw" Coins.

They are sent to the Divine Realm of Domminna through a Magic Circle Ritual.

The Coins are exchanged within the Circle for Wish Scrolls, that are consumed as Wishes are made, burning up the scrolls in red flame.

These Wish Scrolls are usually traded for Speculative Value, kind of like Cryptocurrency. Using a Wish Scroll is not without Consequence.

You have used Divine Power, and now the Divine is vetting you to rise, in a manipulated destiny.

Most educated people just trade Wish Scrolls, knowing the consequences of using them. There are Legends of foolish use of Wish Scrolls.

These stories tell of fools who cause great calamities in Orbspace with generalized wishes.

Once in Domminna, the Raw Coins are refined within Angelic Vessels to transform them into Divine Coins.

The Angelic Vessel Coin Refinement Factory is like a Hyper futuristic version of New York City, where the City is sentient, and Sacred Geometry is expressed in an Architectural Language of Semiotics.

It takes an Angelic Being like Matthios to operate it. He is challenged by it, and it keeps him sharp.

It's not that one Coin Type is better than another.

The different Types just have different Mechanics.
