Make it so that the coin area does not change, for example, put your camera directly overhead. Perhaps use a telecentric lens if you need to. Then you will have constant areas and since each coin value is a different size, you can detect which coin is which just like I did in my coin demo in my Image Segmentation Tutorial.
