I wish I knew... I have a similar occurrence and it is always with dimes and I've yet to find an answer. It started happening to my father and me at the same time and has been going on for the last 12 years. I don't care where I am, I can be in NYC, on a train, I can vacuum my house and out of no where a dime mysteriously appears. Only once did a ten dollar bill mysteriously appear out of thin air (I'd love more of those!). And I save them all! My father once nodded off while watching a program in the living room and woke up with a dime on his belly. In fact, this is where it all started with the dimes for us.
My Dad, who is extremely skeptical, and I both believe there is a significant meaning to the dimes otherwise it would be any coin or bill that just appears. It's always dime's.
Good question, bree. It remains a mystery, maybe somebody here knows the significance.
