Find a penny - somebody is saying hi from heaven

I've been coming across a lot of random pennies lately. When we boarded the flight to Seattle, there was a penny in my seat (I brought it to my mom). When we went out to dinner in Tacoma, we found another (my mom is holding it). And when I flew back to San Francisco, there was another waiting for me by my seat in the airplane. My mom and I guess it's my dad letting us know he's thinking of us during the holidays. He passed away five years ago but is still in our hearts and thoughts.
