Hi my name is sweetdavey I have a 1987 washington quarter that appears to be made from possibly aluminum or some other alloy and also the reeded edge is missing exposing the copper core can anyone tell me anything about this?

Your coin has been exposed to acid or some other corrosive agent and is just damaged, welcome to the forum.
