Doloc Town mineral collectibles use guide
Direct answer
You can sell mineral collectibles in Doloc Town, but a community answer recommends keeping them because they may be requested by a guild board mission. No collected source confirms a museum donation system for these items. If storage allows, saving at least the collectibles you have not yet needed is the lower-risk choice until the relevant board request appears.
Sell now or keep for later
The Reddit discussion supports both actions: mineral collectibles can be sold, and they can have a later guild board use. Selling provides whatever value the current item interface displays, while keeping preserves quest flexibility. The source does not provide prices, mission rewards, quantities, or a list of collectible names.
Because the future request is possible but not fully documented, the decision depends on immediate inventory pressure. Keep the item when storage is available and money is not urgently needed. Sell only with the understanding that another copy may need to be found if a matching board mission appears.
Guild board mission use
The community reply specifically mentions a guild board mission as a reason to retain collectibles. It does not identify the mission title, unlock condition, deadline, or whether every mineral collectible can be requested. Check the current board and read the requested item name before committing anything.
Do not assume that possessing a collectible automatically starts a mission. Board requests may depend on progression or rotation, but the source does not establish either mechanism. Record the exact request, required item, and game version if you encounter one so the claim can become more precise.
No verified museum donation claim
Many farming games use collectibles in museums, but that pattern is not evidence for Doloc Town. The collected material does not confirm a museum, donation menu, collection reward, or curator for mineral collectibles. This guide therefore does not tell players to reserve items for an unsupported feature.
If an in-game interface later identifies a donation destination, capture the name and prompt before updating the advice. Until then, the Dictionary, inventory description, sale interface, and guild board are the relevant places to inspect. Avoid importing mechanics from another game simply because the item is called a collectible.
A practical storage policy
Place unneeded mineral collectibles in a clearly labeled storage container if your farm layout permits it. Keep them separate from ordinary ore and crafting materials so a future board request is easy to check. This is inventory-management advice, not a claim that a specific quantity will be required.
Review the guild board before selling stored collectibles in bulk. Compare the exact item name and icon because similar minerals may not be interchangeable. The source does not establish quality grades, stack requirements, or whether a mission consumes the item immediately.
How to verify a collectible's purpose
Read the current item description first and note every interface that accepts the item. Check the sell screen for the displayed value, then check available guild board requests for the same name. A visible match is stronger evidence than a general statement that collectibles are useful later.
When reporting the result, include the item name, mission wording, required quantity shown by the game, reward shown by the game, and version. Do not generalize one mineral to every collectible without testing. This keeps the guide accurate while the available community evidence remains broad.
Current conclusion
Mineral collectibles have a verified community-reported sale option and a possible use in a guild board mission. Keeping them is the cautious choice when storage is available, while selling is reasonable when immediate funds or space matter more. Exact economics and mission requirements remain to be confirmed.
There is currently no supported basis for claiming a museum donation system. Players should rely on the current item description and guild board rather than expectations from other farming games. Future updates should add specific item-level evidence without inventing a complete collectible checklist.
