Ever since my grandfather died we find dimes quite often, experiences?

I know some people here will check this off as coincidence but I think otherwise. He died nearly 2 years ago, he had these collections of money like collecting 2 dollar bills and dimes many many dimes. Going through his things we found a 5 gallon jug of dimes. So all i'm asking is if anyone has had similar occurrences. I would really appreciate it, Thanks.
