Storeroom Cache beneath the Iron Stair

You clear rubble from a collapsed stairwell in a low, damp dungeon and find a narrow storeroom that someone used as a temporary hoard. There are no signs of recent visitors or the bodies of beasts — just the residues of old maintenance: broken rope, a scorched lamp, and careful packing. The party of four level-4 adventurers has enough experience to recognize useful components and small magic trinkets, so the group gathers coin, supplies, and a few curios that would suit further dungeon exploration.
