Prospector's Kit

In this metal box is a collapsible hammer used to breaking small rocks, a gold pan, a tiny magnifying glass, a handful of brushes, and a scraping tool. It would be common to ask for a Dexterity check when trying to properly scrap clay or rock off of a surface, whereas it might be suitable for a Wisdom check to pick out the fine flakes of gold. An Intelligence check might be called for identifying the difference between silver and Sham Silver.
