Silver chests do not offer much of a reward for completing the shock-a-lock puzzle. I just recently opened one and received nothing! I probably wouldn't have said anything if I had gotten something, but this is just sad. And most of the time, when I compare the wooden chest I opened to the silver chest, I get more gold from the wooden and a better chance (in my opinion) to receive a reagent, treasure card, etc. I think the rewards in silver chests need to be upgraded-- like maybe more gold, a housing item, or just simply a better chance to receive better rewards.
