Lightman's Currency Core Progression: Trading Core, Wallets, and Coins
The core progression in Lightman's Currency starts with the 
Trading Core, the item that anchors your early economy and unlocks the wallets and coins you will rely on. Before you build any machines, you need to understand how the Trading Core is made and how the wallet and coin chain grows from it. This guide covers the crafting recipes and upgrade paths that define your first steps.
Crafting the Trading Core
The Trading Core is a shaped crafting recipe. To make it, you combine six 
Redstone Dust, one quartz gem, a 
Dropper, and a 
Redstone Comparator. The quartz comes from the gem tag, so any valid quartz gem works in that slot. This is the foundation item you need before progressing further into wallets and coins.
Wallets
Wallets are the containers that hold your coins. They come in multiple tiers, and the basic wallet can be dyed any color in the same way vanilla leather armor is dyed. This lets you personalize your wallet without changing its function.
Higher-tier wallets are made through upgrades. The 
Wallet (Iron) can be crafted in two ways. The first is a wallet upgrade: take a basic wallet and an 
Iron Ingot to produce a Wallet (Iron). The second is also a wallet upgrade: take a 
Wallet (Copper) and an Iron Ingot to produce a Wallet (Iron).
There is also a shapeless recipe for the Wallet (Iron): two leathers from the leather tag, one 
Copper Ingot, and one Iron Ingot.
Wallets in the mod are described with several notable properties. They are immune to fire damage. Some wallets are completely invulnerable. Certain wallets also provide bonus coin magnet levels, which affect how coins are attracted to you.
Coins
Coins are produced with a Coin Mint. Each coin type has a mint recipe that converts a raw material into the coin, plus a shapeless recipe that converts a coinpile back into a single coin.
Iron Coin: The Coin Mint turns an Iron Ingot into an Iron Coin. A shapeless recipe converts an 
Iron Coinpile into an Iron Coin.
Gold Coin: The Coin Mint turns a 
Gold Ingot into a Gold Coin. A shapeless recipe converts a 
Gold Coinpile into a Gold Coin.
Emerald Coin: The Coin Mint turns an emerald gem into an Emerald Coin. A shapeless recipe converts an 
Emerald Coinpile into an Emerald Coin.
Putting the Progression Together
Your first priority is gathering the materials for the Trading Core: six Redstone Dust, a quartz gem, a Dropper, and a Redstone Comparator. Once you have the core, you can move toward wallets and coins. The wallet chain begins with a basic wallet, which you can dye, and upgrades toward Wallet (Iron) using either a basic wallet or a Wallet (Copper) plus an Iron Ingot, or the shapeless leather-and-ingot recipe.
Coins come next, and they all run through the Coin Mint. Iron, gold, and emerald each have their own coin, and each coin can be broken back down from its coinpile form with a shapeless recipe. This gives you a closed loop: mint ingots or gems into coins, store them in wallets, and convert coinpiles back into individual coins when needed.
The machines you build first follow from these items. The Coin Mint is the machine tied directly to coin production, and it is the one you will use for every coin type listed here. The Trading Core is the prerequisite item that sits at the start of the chain. Everything else in this early progression builds on the wallet tiers and the coin types you can mint.
