Has anyone ever found entire rolls of just silver?

I am new to the silver world and a month ago I started to CRH. My first search I hit a big score $60fv out of $160. Over the last month I have bought $600+ with no luck. Today I found 3 rolls at a new bank and all of the coins were 40%ers except 1 90%. I know this doesn't happen much, just wondering if anyone else has had this kind of luck?
