The second chest was stolen from a big guy who was also a prominent character of the tribe, the one from whom Ash saved that blonde prostitute with whom he had an appointment for a wonderful night when he returned to town (Chapter 175).
Ash opened the chest and found its contents similar to the previous one: chainmail armour, leather boots, a simple iron helmet, a double-handed long sword, dried fruits, wine bottles, two colourful shirts of human, and metal junk that might be interesting to goblins, so he collected them as a hobby but have no real value.
"Huh? Weird, this guy didn't have a single coin in his chest? Did he hide them somewhere else or..." Ash paused and looked at the dozens of wine bottles in the chest. Remembering that bastard smelling like a pig showered in alcohol, he understood where all the coins went.
