The Throw a Coin Infinity Coin sits at the very top of the twenty-coin ladder. It is the only coin in the entire game that can roll the Omega rarity band, and the Omega band contains exactly one drop: the Dyson Sphere. Owning the Infinity Coin is the prerequisite for chasing the rarest items in Throw a Coin, and it is the single biggest luck lever any player can pull in the game.
This page covers what the Infinity Coin actually is, how it fits into the wider twenty-coin ladder, what it costs (or rather, what the developer has not published), and how to plan your cash flow around buying one. If you have ever wondered whether the Infinity Coin is worth the grind, the answer is yes — but only once you have the supporting systems in place.
What Is the Infinity Coin
The Infinity Coin is the twentieth and final purchasable coin in Throw a Coin. It sits at the top of the wiki's Endgame band alongside Paradox Coin, Miracle Coin, Nexus Coin and Apex Coin, and it is the only coin in the entire game that can roll the Omega rarity band. The band it opens contains a single item, the Dyson Sphere, which is the rarest single-item drop in Throw a Coin below the Galactic-tier Milky Way.
Key takeaways about the Infinity Coin:
-
Infinity Coin is the 20th and final coin in the 20-coin ladder, sitting at the top of the coin progression.
-

Infinity Coin also enables the Galactic band, which contains the Milky Way as the only item.
-
Infinity Coin is required to roll the World 3 plaza fountain, which is the only known source of the Milky Way.
-
It is coin number 20 on the fixed twenty-coin ladder.
-
It is the only coin that can roll Omega rarity.
-
It is the only coin that unlocks the Dyson Sphere drop.
-
It is in the Endgame band of the wiki's four-band structure.
-

How the Infinity Coin Fits the Ladder
The Infinity Coin is the last in a sequence of five endgame coins. The full endgame block, in order, is Paradox Coin, Miracle Coin, Nexus Coin, Apex Coin and Infinity Coin. Each one opens a single rarity band, and the bands march upward from Nebular to Supernova before finally reaching Omega. Buying the Infinity Coin means you already own all nineteen coins below it, which is itself a major achievement given that the developer has not published the price for any coin past Volt Coin.
What the Infinity Coin Unlocks
The Infinity Coin unlocks the Omega rarity band, which is the second-from-top band on the twenty-four-rarity ladder. Omega sits one tier below the top band, Galactic, and the only item in the band is the Dyson Sphere. Because the Infinity Coin is the only coin that can roll Omega, every Dyson Sphere drop in the game comes from a player using the Infinity Coin at the magic fountain.
| Property | Value |
|---|---|
| Coin slot | 20 (top of ladder) |
| Rarity band unlocked | Omega |
| Items in band | Dyson Sphere |
| Wiki band | Endgame |
| Coin below it | Apex Coin (Supernova) |
| Coin above it | None — Infinity Coin is the cap |
| Rarity band above | Galactic (Milky Way) |
Why Omega Is So Hard to Roll
The Dyson Sphere is one of the rarest items in Throw a Coin, and the only way to roll it is to have the Infinity Coin equipped. That makes the Infinity Coin the single highest-impact equipment swap in the game. The Galactic band above it is even rarer, with the Milky Way described in the official Roblox game description as a 1 in 20 quadrillion drop, but the Galactic band is gated by sheer luck volume rather than by which coin you have equipped.
How to Get the Infinity Coin
The Infinity Coin is bought at the coin stall beside the magic fountain, just like every other coin on the ladder. The exact price has never been published by the developer, and any specific number you see for the Infinity Coin outside this wiki is a community estimate. The general path to affording one looks like this.
-
Own all nineteen coins below the Infinity Coin first. The coin stall does not let you skip tiers.
-
Push your Luck Multiplier upgrade to a level where high-rarity drops are common.
-
Fill the Index as completely as you can. Every new entry adds permanent passive luck, and that bonus carries over to Omega rolls.
-
Use the Mutation Machine to convert duplicate mid-band items into Big, Huge, Rainbow, Astral and Divine variants. The cash from a single Divine drop of a high-band item can cover large chunks of the Infinity Coin price.
-
Run during the ADMIN ABUSE + WORLD 3 event window (2026-07-26 to 2026-08-02) for the 3x boost that comes with the event title prefix.
The Index Multiplier Is What Makes the Infinity Coin Realistic
The single biggest unlock for the Infinity Coin is finishing your Index. Every new item you discover — including every mutation of every item — adds permanent passive luck, and that passive luck multiplies on top of the Infinity Coin's base luck. A player with a nearly complete Index will roll Dyson Spheres at a meaningfully higher rate than a player with an empty Index even though both have the same coin equipped.
Infinity Coin vs Coins Below It
The Infinity Coin is not always the right coin to have equipped. There are situations in which a lower-tier coin is actually the better choice, especially when you are grinding Index entries from a specific band. The list below covers the most common trade-offs.
| Scenario | Better Coin | Why |
|---|---|---|
| Chasing first Omega drop | Infinity Coin | Only coin that can roll Omega |
| Filling mid-band Index entries | Eclipse, Mirage or Obsidian | The drop pool is too narrow at Infinity Coin to make index-farming efficient |
| Mutation farming | Apex Coin | Slightly broader drop pool than Infinity Coin at much lower cash cost |
| First time hitting Supernova | Apex Coin | Cheaper, and the items are nearly as valuable |
| Late-night overnight farm | Apex Coin | You will not roll Omega in a sleep cycle anyway, and the cash flow is steadier |
Why Apex Coin Is the Best Companion Coin
The Apex Coin opens the Supernova band, which contains Betelgeuse and Quasar. Both items sell for a lot of cash, and the drop pool is wide enough to make overnight farming productive. A common pattern among experienced players is to use the Infinity Coin for focused sessions and switch to Apex Coin for long background farms.
Strategy for Once You Own the Infinity Coin
Owning the Infinity Coin is not the end of the progression. The real game after the Infinity Coin is the Galactic band, the Mutation Machine, and the Worlds portal. The advice below covers how to actually use the Infinity Coin once you have it.
-
Run focused sessions with manual throws. The Perfect Throw timing bar is worth up to 2.00x on a single toss, and that bonus is the cheapest way to push your Omega odds. Auto Throw at 100% kills the Perfect Throw bonus, so save the Infinity Coin for manual play.
-
Pair it with the Mutation Machine. Every Omega drop is a candidate for a Divine mutation. Divine Omega drops are the single most valuable objects a player can hold.
-
Stack Item Value after your Index is full. Once your Index is complete, Item Value becomes the next best cash-per-throw upgrade because the rarity drops are already as good as they are going to get.
-
Watch the Worlds portal. World 3 launched on July 26, 2026 as a limited event, and the developer has not confirmed whether it will become permanent. If World 3 stays, the Infinity Coin is even more valuable in that map.
Endgame Item Reference
The table below lists the items that become available as you approach the Infinity Coin. These are the items the Infinity Coin can roll directly, plus the bands above it that the coin can also reach as side drops. The list covers every rarity from the Late Game block through the top of the ladder.
| Band | Items | Coin That Unlocks It |
|---|---|---|
| Quantum | Quantum Cube, Impossible Cube | Eclipse Coin |
| Universal | Black Hole, Singularity | Mirage Coin |
| Omniversal | Infinity Door, Infinity Crown | Obsidian Coin |
| Absolute | Antimatter Reactor, Reality Core | Tempest Coin |
| Stellar | Mars, Moon | Soul Coin |
| Nebular | Saturn, Jupiter | Paradox Coin |
| Solar | Sun | Miracle Coin |
| Zenith | Sirius, Spaceship | Nexus Coin |
| Supernova | Betelgeuse, Quasar | Apex Coin |
| Omega | Dyson Sphere | Infinity Coin |
| Galactic | Milky Way | No named coin (side drop) |
The Infinity Coin is also the only coin in the entire twenty-coin ladder that can roll items in the upper half of the rarities table, which is what makes it the most consequential purchase in any save.
