Steps:

"I need to find the value of a coin in the image"

1. Preprocessing (If required)
2. Segmentation (ROI)
3. Apply Sort of Morphological Operations (If Required)
4. Apply the bounded Box
5. Use OCR

"its diameter and area"

1. Preprocessing (If required)
2. Apply the CHT or use the Circular Object Detection Method Link
3. You may get the detais in resultant structre

If you are using another approach to obtain circular objects to obtain area and diameter, please use the regionprops function.
