Undermine Coins in WoW Forever: What a Coin Is Worth

The short answer

The "Undermine coin" players talk about in WoW Forever is, in the beta client, the Tarnished Undermine Real: currency id 3469 and item id 226404. You can hold at most 165 of them. The client's cost table charges Reals at twelve different prices, from 3 to 150, so the most expensive thing you can buy with them fits under the cap with room to spare.

A Real has no gold price, and it never will on the Auction House: the item binds when picked up, so no player can sell you one. Its worth in gold is whatever the things it buys are worth. The client does not tell us what those things are, because vendor stock lives on the server. So the honest answer to "what is a coin worth" is a method, not a number, and this page gives you the method and every fact the client does prove.

What the client says

Two small details are worth reading closely. The currency text says the Reals are spent "at goblin towns throughout the Eastern Kingdoms and Kalimdor", which points to goblin vendors rather than one central shop. And the item's stack size of 250 is larger than the currency cap of 165. When an item converts into a capped currency, coins above the cap usually cannot be added. If you are close to 165, spend before you loot more.

The Real is not new to Classic as a whole. It was the currency of a Season of Discovery phase in Classic, and the client still carries its Season of Discovery item id. What is new is its place in Forever, alongside Forever's own currencies.

The twelve prices in the cost table

The client keeps a table of extended costs: the non gold prices vendors can charge. Seventeen rows in the beta client charge Tarnished Undermine Reals, at these twelve amounts.

Here is what the table tells you even without knowing the items. Most of the rows cluster from 50 to 150 Reals, so the things worth buying are priced in the tens and low hundreds. The single most expensive row, 150, takes 91% of your cap. That means you can save up for the top item, but only just: you will not be able to hold enough for two big purchases at once. The cap is designed to make you spend.

Why a Real has no gold rate

On a normal Auction House, any tradeable thing has a gold price because someone will sell it to you. The Real breaks that in two ways.

1. It binds when picked up. You cannot trade Reals, mail them or list them. There is no market price, and our scans will never show one.
2. The crates bind too. The client has three versions of a Damaged Undermine Supply Crate, uncommon, described as looking like it "quite literally fell off the back of a zeppelin". All three bind when picked up. If Reals come out of crates, the crates cannot be sold either.

So a Real is worth exactly what it saves you or earns you. That is the only honest way to put a gold figure on it.

How to value a coin yourself

When you stand at a goblin vendor that takes Reals, use this method. It takes a minute and it stops you spending coins on the wrong thing.

1. Find the item's Auction House price. If the thing the vendor sells is tradeable, look it up on the beta Auction House or in our price strips.
2. Divide by its cost in Reals. That is the gold value of one Real spent on that item.
3. Do the same for every item on the vendor. The best purchase is the one with the highest gold per Real.
4. For untradeable items, ask what you would pay. If it is gear or a convenience you would otherwise buy, use the gold you would have spent.
5. Spend before the cap. Coins above 165 are coins you cannot keep. A purchase at a slightly worse rate beats a wasted coin.

Here is the same method as a template you can fill in.

When we can confirm real vendor rows on the beta, we will fill this table in with items, Real costs and live prices.

What the cost tiers suggest about value

Even without the vendor rows, the shape of the cost table says something about how Blizzard has priced the Real.

The cheapest rows, at 3, 5 and 10 Reals, are the kind of price vendors put on consumables: something you buy often and use up. The middle band, 15 to 35, has one row at each step, which reads like a ladder of small upgrades. The heavy band, 50 to 150, holds ten of the seventeen rows. Those are the purchases the currency is really for, and they are spread across five price points, so there is a choice to make at each level of saving.

The cap of 165 then sets the pace. If you earn Reals steadily, you will hit a decision every time you pass 50, 75, 100 and 125: spend now on a mid tier item or keep saving for the 150 row. Because the cap sits only 15 above the top price, you cannot save for two top purchases in a row. Spending is built into the design.

For a gold maker, that structure means two things.

1. The small rows are where coins turn into gold most reliably. Consumables at 3 to 10 Reals are the most likely to be tradeable, and the most likely to have a steady Auction House price you can compare against.
2. The big rows are where coins save you the most gold. If the 150 Real item is gear you would otherwise buy from a player, its gold value may be far higher than any consumable, but only to you, not to the market.

When the vendor rows are confirmed, the first thing we will publish is the gold per Real for every tradeable item, sorted from best to worst. Until then, carry the method above and fill it in at the vendor.

Where Reals come from

Player reports from the beta describe Undermine coins dropping from dungeon bosses and being exchanged for gear and crafting materials. We have not confirmed drop sources, so we do not list any. The currency text's "goblin towns" fits the beta's new goblin port: Powderfuse Port in the Riverglades, which players also report as the home of the Black Market and of Mister Graphed. If you are in Powderfuse Port for either of those, check whether a goblin there takes Reals.

Reals against Forever's other currencies

Forever's client has two other economy currencies worth comparing.

Merchant's Favor is described in the client as "Worth a considerable amount of gold". It is tied to crate turn ins, and the Legacy perk Performance Bonus gives a 15% chance of 100% more Favor when you turn in a crate. Our Legacy Points guide covers that perk. Its prices run far higher than the Real's, up to 6,000, so the two currencies are clearly built for different scales of purchase.

Practical advice

• Never let Reals sit at the cap. At 165 you lose every coin you loot.
• Spend on tradeable items when the rate is good. A purchase you can resell turns Reals into gold.
• Keep one big purchase in mind. The 150 Real row is the top of the table; know what it is before you spend small.
• Do not chase crates for gold. They bind on pickup. Their value is only what is inside.
• Check the strips first. Our Auction House guide explains how beta prices reach this site.
