Too many silver boxes

In the past 3days I have gotten 5 silver boxes. I really want to open them but can't due to not having enough coins.
I was wondering what ppl have generally gotten from the boxes so I can see if they r worth getting coins for to open
Thanks

if you click on the box you can see what is available.

I opened 2 silver boxes, one on s48 and one on s105. I've got a nugget on s105 and a crown on s48.

I would sell npc. Safest way to go and u get 20k.

Opened 2 got 7 enhancement stones and then 32k gold.

Thanks for the help
