Pennies From Heaven?

Back in April of this year, I responded to a question on Quora. For those who don’t know, Quora is a social media Q&A platform. Users ask and/or answer questions on a myriad of subjects. The question I answered was: “What is the scariest unexplainable thing that ever happened to you?”
     I have had an interest in the paranormal since childhood, but as I matured, I developed a healthy skepticism in the sense that I attempt to find a reasonable explanation for something that seems magical or supernatural. However, the narrative I wrote about on Quora continues to baffle me. Perhaps you, the reader, can offer a better explanation than I for how an ancient Greek or Roman coin dropped into my bedroom out of thin air.
     To give a little background, after my sister Susan died, I began finding pennies in unexpected places—the middle of my bathtub or inside a slipper, for example. Of course, I find pennies in places you might expect to find them, such as on the ground or a table or the floor of my car. Since I find pennies in all these places, both expected and unexpected, I wonder if each time I find a penny, is it a sign from Susan? Common sense would tell me no, but here’s an incident I cannot explain: I had just taken a shower and walked naked into my bedroom. I picked my nightgown up from the bed and slipped it over my head. As the nightgown slid down my body, I heard “plink”—the sound of a coin falling onto the floor. The coin (shown below) is smaller and much thinner than a U.S. penny, and thousands of years older.

     Having an interest in the supernatural, I recalled hearing the word apport, which is French for to bring. An apport is an object that appears by seemingly spiritual means. Supposedly, Mediums could apport objects during seances, but I believe most of those instances are hoaxes.
     I searched my memory for any way I may have come upon this coin. The only circumstance I recall was a visit I had made to The British Museum in London where I saw a display of Greek and Roman coins. But that was fifteen years ago, and I did not purchase any ancient coins as keepsakes. I had never seen this coin before.
     The question, where did the coin come from, and who sent it remained. As I mentioned earlier, I had written about this coin in Quora. I had dictated rather than typed the narrative into my iPad, and I spoke the words, “I wonder if my sister sent it.” Instead of typing the word “it” the word auto-corrected to the word “yes.” I tried repeating the word “it” many times, and the iPad continued typing “yes” until finally I realized my question was being answered. Yes! The coin is from my sister. Once I made the connection, I had no further issue with typing the word “it”.
     I haven’t yet taken the coin to a collector. I’ve looked at Greek and Roman coins on the internet, but haven’t found an image of the exact coin. Several readers suggested the coin might be worth a lot of money, but from what I could find out, the monetary value of the coin is around forty U.S. dollars. To me, however, this coin is a gift from the spirit world, a precious priceless gift from Susan.
