It weighs almost nothing and stacks to 9,999, so there is no reason not to carry a full stack. It sells for almost nothing, so do not bother hauling it to a shop.
Where to Find Copper Key
1 Pal drops Copper Key when defeated or captured, which is usually the faster route if you are already out hunting — the drop list below is sorted by how reliably each one gives it up.
It also shows up as world loot — chests in the Grasslands, junk hauls while fishing in the Grasslands and fishing in the Grasslands, and 1 more pool besides, usually 1–2 at a time. Higher-grade chests carry the better rolls, so the ones guarded by a camp are usually worth the detour.
Chests inside 3 caverns, including Hillside Cavern and Isolated Island Cavern, can hold it as well.
