Is there a coin or a pair of copper coins hanging in the bedroom?

One. The five emperors' coins used in geomantic omen are generally arranged above the door in the order of Shunzhi, Kangxi, Yongzheng, Qianlong and Jiaqing. If it's a single shipment, it doesn't matter if there is no order. Generally, it is most suitable to hang on the top pillar and the door. Note: The answers are for reference only. Please don't be blind and superstitious.
