Hm, I don't think it's random?
metal - same as you, Ariana, plate armour
gold => 5000 gp
wood => Entwood bark? (had the German version, hope translation is correct)
stone => 2handed hammer?
The hammer & the Bark sound familiar. The gold is right...
Hmmm... Maybe I was wrong about the other chest. I thought it was a sword, but I can't really remember. I DO recall I wasn't at all impressed by whatever it was...
