When I was a kid, I was sent to Sunday school, and my coin offering was tied in a hanky with a knot so tight I couldn't untie it myself. I'd check for a coin.
I felt the top there it felt there was nothing in it I thought was some type of doll for like a child or something or maybe there was writing on the cloth
