When I was young about 4 or 5 I had a skin pouch underneath my skin I use to ask my mom for pennies so I can put them in the skin flap underneath my feet then give them to my sister to put in her ear to “preform” a magic trick, I would also do this about 4 times each week , later on I got an infection and had to be put on medicine… I will never put coins in my skin flap ever again.
