Is this creepy or a sign??

I was cleaning out our spare room when I found this wedged between a piece of molding and the wall. At first I was like hell yeah a 5 dollar bill!But when I opened it up I realized there was a picture of a baby on it!!!! My husband thinks it’s creepy, but I think it might be a sign of good luck for our ttc journey and I don’t want to spend it! What do you think?
