Answer:
I have no bed to sleep and no palace to live. I don't have a single coin but I am known as king. What am I?
Although a human shape I wear Mother I never had; And though no sense nor life I share in finest silks I'm clad. By every miss I'm valued much beloved and highly prized; still my cruel fate is such by boys I am often despised.
I'm simple for a few people, but hard for them to hear. I live inside of secrets and bring people's worst fears. What am I?
Use me to reward good behavior.
Some will use me, others not. Some have remembered, others forgot. For profit or gain, I'm used expertly. I can't be picked off the ground or tossed into the sea. What am I?
No matter how little or how much you use me, you change me every month.
