This guide will explain when each "archaeological find" gets available in the digging site.

To start digging, talk to Carter while he's at the digging site, in front of his tent.
You can dig from 10AM to 5PM everyday, except on days 3 and 4.

The archaeological items are divided into 6 types:
- Coins
- Fossil
- Stone Objects
- Ores
- Golden Objects
- Stone Tablets

Rarer and more expensive Archaeological items get added to the digging site, according to your in-game chapter
Here's a list of items that get "unlocked" every chapter:

These are the items you will find most of the time.

• Coin - 40G
  
• Clay Figurine - 60G
  
• Moonlight Ore - 100G
  
• Leaf Fossil - 50G
  
• Golden Fork - 1000G

These items are a little harder to get, but still very common.

• Silver Coin - 80G
  
• Clay Horse - 100G
  
• Sugarstar Ore - 200G
  
• Fish Fossil - 40G
  
• Golden Comb - 1500G

Here things start to get hard. These items are a lot harder to find compared to the previous ones, but still not "impossible".

• Magatama Stone - 200G
  
• Shell Fossil - 60G
  
• Hexagonal Ore - 600G
  
• Golden Fish - 2000

Not much to say here. To get these, you are going to have luck and be persistent.

• Golden Coin - 120G
  
• Strange Object - 300G
  
• Mete-Ore - 800G
  
• Marine Fossil - 100G
  
• Golden Crown - 2500G

Ok, so this is where things get REALLY HARD! getting those will consume a lot of your time, and unless you want to 100% your Encyclopedia, I won't recommend looking for them. By this time in the game you probably won't need to keep digging for money.

• Stone Wheel - 1000G
  
• Footprint Fossil - 250G
  
• Millennium Ore - 1200G
  
• Golden Bear - 3000G

I'm already at Chapter 7 (about 1 year and half [in-game time]) and I COUND'T FIND A SINGLE GOLDEN BEAR!!!

The Stone Wheel is the most common one apparently, since I found 2 of them.
I also found 1 Footprint Fossil after a long time digging.

Gathering all 6 Stone Tablets is actually a lot easier and less painful than finding the other archaeological finds.



Every Chapter adds a new one (starting from chapter 1, going up to chapter 5).
Just keep digging until you find it.

Chapter 1
- Stone Tablet C

Chapter 2
- Stone Tablet D

Chapter 3
- Stone Tablet E

Chapter 4
- Stone Tablet F

Chapter 5
- Stone Tablet G

(Not sure why they didn't made the A and B tablets.)

Spoilers about the reward for gathering all 6:
Gathering all stone tablets will unlock a cutscene involving Lou, Carter, Flora and the MC.
They reveal that the stone tablets actually translate to a curry recipe.


(I'm doing some experiments to confirm if you can get a stone tablet from a previous chapter in a later one. Going to update this guide later with the results)

A special thanks to Neoseeker for providing the sell price of each item AND information about the Golden Bear. Gathering and selling every item again just for checking selling values would be really boring.

Hope this guide helps! Now I'm on my way to find the legendary Golden Bear! Byee!
