Where in the world are you located? You mentioned ferrous and non-ferrous coins.

How many denominations do you have and, could you describe, for each denomination...
- the diameter,
- any center cutout/hole,
- any bimetallic center piece,
- mass,
- element or alloy.

Also, the expectations of the machine
- (only identify or sort too?
- if only identify, what type of signaling do you use (led combination, buzzer, other)
- what rate will the coins pass
- how much space/time between coins
- what type of space constraints will the coins be within?
- any chance to move the coins to the same position on the belt?
- anything else we should know?
