Gunther is kind of a mystery. He sits behind that massive blue desk in the Pelican Town library, surrounded by empty shelves and dusty air, waiting for you to do all the heavy lifting. If you’ve spent more than twenty minutes in Pelican Town, you know the drill. You find a weird rock or a rusty spoon, the item description says "Gunther can tell you more about this," and you dutifully hand it over. But honestly? Completing the Stardew Valley museum collection is a long game that most players mess up by being too generous, too early.
It’s tempting to clear out your inventory. You see an empty slot, you want to fill it. But some of those "artifacts" are actually high-tier crafting components or keys to late-game secrets. If you give away your first Prismatic Shard just to see it sit on a shelf, you’ve basically locked yourself out of the strongest weapon in the game for potentially dozens of hours. That’s a mistake that stings.
The Brutal Reality of the 95-Item Grind
The museum isn't just a side quest; it's a massive 95-item checklist. You’re looking for 42 different minerals and 53 unique artifacts. Most of these come from tilling soil—those little "artifact spots" that look like three wiggling worms—or cracking open geodes at Clint’s shop.
The drop rates are brutal. Some items, like the Prehistoric Scapula or the Elvish Jewelry, have such low spawn percentages in certain areas that you’ll find yourself circling Cindersap Forest every morning like a man possessed. It’s not just about luck; it’s about knowing which "trope" of RNG you’re fighting. For example, the Rib Bone is common in the Mines, but the Vertebrae? You better start hoeing the dirt at the Bus Stop.
Rewards That Actually Matter
Gunther isn't totally cheap. He does give you stuff back. Once you hit certain milestones, he starts handing over seeds and furniture. Some of it is fluff. You get a "Standing Geode" or a "Bear Statue" that just takes up space in your farmhouse. Whatever.

But then there are the heavy hitters. At 60 items donated, Gunther gives you the Rusty Key. This is the big one. It unlocks the Sewers, which gives you access to Krobus, a literal shadow person who sells Void Eggs and the Stardrop. Without that key, your progress basically hits a brick wall. You also get Ancient Seed packets for donating the Ancient Seed artifact. That’s the foundation of any real late-game profit empire. If you don't plant those immediately, you're leaving millions of gold on the table.
The Mineral Trap: Don't Donate These Yet
Minerals are easier to find than artifacts because geodes are everywhere. You go to the mines, you kill some slimes, you come back with twenty Frozen Tears and Earth Crystals. But hold on.
Earth Crystals are a core ingredient for Mayonnaise Machines. Fire Quartz is needed for Solar Panels. And then there’s the Marble. Marble is notoriously annoying to find because it only comes from regular Geodes and Omni Geodes. You need one for the Marble Brazier recipe to get the "Craft Master" achievement. If you donate your only Marble to Gunther, you might spend the next two seasons praying to the RNG gods for another one just so you can finish your crafting list.
The Prismatic Shard and Dinosaur Egg Dilemma
This is where most new players feel the soul-crushing weight of regret.

- Prismatic Shards: These are the rarest minerals in the game. Gunther wants one. Don't give it to him. Not yet. Take that shard to the Three Pillars in the Calico Desert first. It transforms into the Galaxy Sword. Once you have the sword, the mines become a joke, and finding a second shard becomes way easier.
- Dinosaur Eggs: You might find one fishing or in a Pepper Rex floor in Skull Cavern. It looks like a museum piece. It isn't. It’s an egg. Put it in an incubator in a Big Coop. It hatches into a dinosaur. That dinosaur will then lay more eggs. Give Gunther the second or third egg, never the first.
Where Everyone Gets Stuck: The Artifact Spot Science
You’ve probably noticed that the items you find in the dirt change based on where you are. The Stardew Valley museum collection is geographically locked. If you’re looking for the Trilobite, you need to be at the Beach or the Cindersap Forest. If you’re looking for the Golden Mask, you're headed to the Desert.
The problem is the seasons. In Winter, artifact spots are much more common because of the Winter Root and Snow Yam mechanics. This is the best time to hunt. Many players ignore the dirt in Summer and Fall because they’re focused on crops, but that’s how you end up in Year 4 still looking for a "Dried Starfish."
The Secret of the Artifact Trove
If you’re tired of digging holes like a frantic dog, talk to the Desert Trader. You can trade 5 Omni Geodes for one Artifact Trove. This is the pro strategy. Artifact Troves contain a massive variety of museum items that are otherwise a nightmare to find. It’s essentially a loot box for historians. Buying these in bulk is the only way most people actually finish the collection without losing their minds.
Completionism and the Final Reward
What happens when you actually finish? When that 95th item clicks into place? Gunther gives you the final Stardrop. It increases your maximum energy permanently. For many, this is the final hurdle for the "Perfection" tracker on Ginger Island.
But honestly, the museum is more about the layout than the items. Since you can rearrange the collection by clicking the small paper on Gunther’s desk, many players turn it into a color-coded art gallery. You can group the minerals by Roy G. Biv order or separate the bones into a "prehistoric wing." It’s one of the few places in the game where you can actually show off a bit of aesthetic flair that isn't just your farm layout.
Practical Steps for Your Collection
Stop donating blindly. If you want to finish the collection without sabotaging your farm's efficiency, follow this logic.
- Check the Wiki or an app before donating any mineral to see if it’s used in a crafting recipe you haven't finished yet.
- Keep your first Dinosaur Egg and hatch it.
- Keep your first Prismatic Shard for the Galaxy Sword.
- Save your Omni Geodes to trade for Artifact Troves once you reach the Desert.
- Target specific zones for the last few artifacts. Use the hoe on every wiggling worm you see in the Railroad and Bus Stop areas, as those are often the most overlooked.
- Rearrange your museum periodically. It makes it much easier to see which slots are missing so you can cross-reference with a checklist.
The museum isn't a race. It’s a slow accumulation of Pelican Town’s history. Just make sure you aren't sacrificing your best gear just to make Gunther smile. He’s fine. He’s been there for years; he can wait another season for your Aquamarine.
Once you have the Rusty Key in hand, focus on the artifacts. The minerals will come naturally through mining, but those rare bones and statues require intent. Start hoarding those Omni Geodes now—you'll need them for the Trove grind later.
