How to Evolve Gimmighoul: Chests Beat Roaming Coins by Nearly 9-to-1

Verified against Pokémon Scarlet and Violet’s current build, 2026. Gimmighoul is the only Pokémon in the mainline series that evolves on a currency threshold instead of a level, a stone, or friendship. You need exactly 999 Gimmighoul Coins, and both forms of Gimmighoul feed the same shared coin total — but they don’t feed it at the same rate. One form is worth roughly nine times as much per encounter as the other, and that gap is the entire strategy.

Quick Start: The Fastest Path to 999 Coins

1. Catch a Chest Form Gimmighoul early — any level works, since coins are a shared bag item, not tied to the Gimmighoul you keep.
2. Ignore Roaming Form coin pickups at first. They’re common but low-value; treat them as a bonus, not a plan.
3. Work through Paldea’s watchtowers and ruins, opening every Chest Form Gimmighoul you find in battle.
4. Track your coin total in the Bag — once it crosses 999, level up your kept Gimmighoul in a wild battle or with Rare Candy.
5. Expect to clear 999 before you’ve even finished the region if you prioritize chests over roaming spawns.

The Two Forms, and Why the Difference Matters

Chest Form Gimmighoul hides inside treasure chests at the top of watchtowers and inside most ruins across Paldea — Dexerto’s location survey counts 25 of them total, concentrated at watchtowers with a few more tucked into ruin interiors[3]. You fight and catch a Chest Form the same way you’d catch any wild Pokémon, and every one you clear pays out coins on defeat[6].

Roaming Form Gimmighoul is different, and this trips a lot of players up: it wobbles around on top of rocks, signposts, and bridges, making a coin-jingling sound when you’re close, but in the base game you cannot catch or battle it. Walking up to one just triggers a coin payout and it vanishes[5]. The only way to own a Roaming Form Gimmighoul at all is to catch one in Pokémon GO and later transfer the Gholdengo it evolves into back through Pokémon HOME — the raw Roaming Form itself never enters Scarlet or Violet[5].

Don’t confuse Gimmighoul Coins with the Amulet Coin held item — they’re unrelated systems that happen to share the word “coin.” Amulet Coin doubles prize money from trainer battles; Gimmighoul Coins are a separate Bag item that exists only to feed one evolution.

The Coin Math: Why Chests Win by Nearly 9-to-1

Here’s the calculation no other guide runs. Serebii’s tested drop tables give exact probabilities for both forms, and multiplying each payout by its odds produces the expected value (EV) per encounter[1]:

Running the weighted average: a Roaming Form interaction nets about 4 coins. A repeat Chest Form encounter nets about 37 coins — roughly 9.25 times more per pull[1]. But that comparison actually understates the real gap, because it ignores the best-kept detail in the whole system: a Chest Form’s first defeat is guaranteed 50-80 coins, not a random roll off that table[1].

That guarantee is what makes a single playthrough sweep so strong. Multiply the 25 known chest locations by the 50-80 coin guaranteed range, and a clean first-time clear of every chest averages around 1,625 coins — comfortably over the 999 threshold even in a below-average run, since even the worst case (all 25 chests landing on the 50-coin floor) still produces 1,250 coins[1][3]. You don’t need to grind respawns or roaming spawns at all to evolve your first Gholdengo. You need to find the chests.

The Fastest Legit Route

Because the first-clear bonus is per-chest and one-time, the actual optimization problem isn’t “which spawn gives more coins” — it’s “don’t skip chests.” Work Paldea region by region instead of chasing chests in the order you stumble on them:

• South Province Areas 1-6: the highest concentration of watchtowers early in the story — clear these as your route naturally passes through.
• West and East Province ruins: chests sit inside ruin interiors here, not on towers, so check inside structures, not just their exteriors.
• Glaseado and Casseroya-adjacent towers: often skipped because they’re off the main path — worth a dedicated detour since each is still a guaranteed 50-80 coin hit.

Once every chest is cleared, the picture changes for a second Gholdengo, since evolving consumes all 999 coins at once[2]. Here the sourcing genuinely disagrees: Dexerto’s location guide states Chest Form “does not respawn” once looted[3], while Serebii’s tested mechanics page states each Chest Form has a 5% chance to try to respawn every in-game day[1]. We’re trusting Serebii here — a flat 5%-per-day chance is a specific, testable claim, and it’s consistent with players occasionally reporting a “new” chest at an old location weeks later, which a hard “never returns” rule wouldn’t explain. If you’re farming toward a second Gholdengo, revisit old chest sites periodically rather than writing them off, but don’t rely on it as your primary plan — treat Roaming Form pickups (50% daily respawn chance, per Serebii[1]) as the more reliable, if slower, backup route.

Priority by Player Type

Triggering the Evolution

Once your Bag shows 999 or more Gimmighoul Coins, level up the Gimmighoul you want to evolve — in a wild battle, a trainer battle, or with Rare Candy or EXP Candy — and it evolves into Gholdengo immediately, consuming the full 999 coins in the process[1][2]. If you’re holding more than 999, the Coin Man in Medali automatically banks the overflow, up to just over 4.29 billion coins, and returns it to your Bag once your total drops back below 999[1]. That overflow system is the safety net for exactly the scenario above — sweep every chest, bank whatever spills over 999, and it’s waiting for your next Gimmighoul.

Is the Grind Worth It?

Gholdengo is a Steel/Ghost type with a 133 base Special Attack and a signature move, Make It Rain, that hits for 120 base power as a Steel-type special attack learned at level 56[7]. Its signature ability, Good as Gold, blocks incoming stat-lowering moves and ability-changing effects entirely — a defensive layer most Pokémon don’t get[7]. That combination of a hard-hitting signature move, a high offensive stat, and an ability that shuts down status manipulation is why Gholdengo shows up in competitive Generation IX teams despite the currency-gated evolution putting most casual players off. The grind is a one-time cost; the payoff is a Pokémon that keeps its niche patched into most formats it’s legal for.

Pokémon GO’s Version of the Same Grind

Pokémon GO runs an almost identical currency gate, but the mechanics that feed it are built around GO’s own systems rather than Paldea’s map. Roaming Form Gimmighoul in GO is catchable — unlike its Scarlet/Violet counterpart — and coins come from catching it, walking with it as your buddy, and spinning Golden PokéStops[4]. It’s also the only Pokémon in GO that can’t be evolved with Candy at all, making the coin requirement a hard, uncapped grind rather than the fixed cost every other GO evolution uses. If you’re working both games side by side, our Pokémon GO special evolutions guide covers the full list of item- and mechanic-gated evolutions GO uses outside standard Candy, Gimmighoul included.

The postcard system is the one bridge between the two: sending a Postcard from GO to Scarlet or Violet delivers a batch of 50-100 Gimmighoul Coins directly into your SV Bag, no chest-hunting required[2]. It’s a slow trickle compared to a chest sweep, but it’s free coins for players who already play both games.

Frequently Asked Questions

Do I need to keep the same Gimmighoul for all 999 coins?

No — coins live in your Bag as a shared item, not attached to a specific Gimmighoul[6]. You can catch a Chest Form on day one, ignore it for the rest of the game, and it’ll still be sitting at 0 coins away from evolving the moment your Bag total crosses 999. This is different from level-based evolutions like Bidoof’s evolution into Bibarel, where progress is tracked per-Pokémon — Gimmighoul’s currency gate makes the specific individual you’re leveling almost irrelevant until the last step.

Is grinding Roaming Form coins ever worth it?

Only as a supplement once you’ve already cleared every chest, or while you’re waiting for chest respawns to reappear. At roughly 4 coins per interaction against a 50% daily respawn chance, it’s a reliable trickle, not a route — treat it as something you pick up while traveling, not a destination.

What happens to leftover coins after evolving?

Nothing is lost if you’re above 999 — the Coin Man in Medali holds the overflow and restores it once your total dips under the cap again[1]. If you’re exactly at 999, evolving zeroes you out completely, and a second Gholdengo starts the whole grind over.

Why does one guide say chests respawn and another says they don’t?

This is a genuine, unresolved disagreement between sources rather than one side simply being outdated. Serebii’s mechanics testing documents a specific 5% daily respawn chance per chest[1]; Dexerto’s location guide states chests are one-time only[3]. We lean toward Serebii’s number because it’s a precise, falsifiable claim rather than a general impression, but if you’re depending on chest respawns for a second Gholdengo, verify in your own save rather than assuming either source is definitive.
