Anyone believe in ghosts or after death communication?

I’m going to try to make this story as succinct as possible. My grandfather and grandmother and my grandfather’s sister, who he was really close with all died within in the same year and a half period. My grandfather was the last to die and he was living with my family when he died and he died in our house. After he died, my mother and I started finding pennies in random places around the house and all the pennies were from 1935, 1939, and 1933, the years they were all born. We found over 20 pennies, all from those years. This is my only “paranormal” experience. I really have no explanation for these pennies.
