hani - since this is a mini-project, then it sounds like school work. Presumably you have been taught something in class that can be used to solve this problem. What have you learned? What has you tried so far?

well,,,,for now i am trying to use the diameter and centroid of a coin to differentiate between each one...however the question is how do i display the camera and test the coin?,,,another thing,,,should the cam distance be fixed ?

hani, you'd have to create a feature vector consisting of things like the color, mean texture, circularity, area, etc. Then you could use a classifier like treebagger to determine the coin, or just do it manually with a bunch of if/else statements.

Or maybe you could use the cascade detector in the Computer Vision System Toolbox.
