The Sovereigns are a little different than any other detector in the fact it gives you much info and let you decide what to dig and what not to. In this case the disc and notch are to be left off (counter clockwise all the way) so you can hear all the different tones and look at the meter if you have one for ID numbers. Now even with the disc and notch all the way off the Elite will not pick up small iron, so what you hear will be all the non ferrous items starting with the low tones of alum foil and going to the higher tones of copper and silver depending on the conductivity of the target. Now some will turn up the disc until it will disc out the smaller pieces of alum foil, but not much higher as you will lose nickles and gold rings too. Now if you ever use notch on any detector you know that this is another disc that is set higher than what the reg disc is set at and only covers a small area of disc. So now if you have no disc or very little disc you can swing the coil over any item you don't want to pick up like a pull tab and turn the control until it will null on this target. Now when the detector sees this target it will be a broken signal or a null. Both the disc and notch will not reject alum screw caps, or our zinc coated pennies we have here or anything higher reading. I think you will find most that use the Sovereign, Elite or the GT run no or very little disc and use notch only when one target is really a problem one, we go by the tones to tell what is good or bad targets.
It takes time, but it is one great detector.
For hammered coins I feel you will have to run no disc or notch at all so you will only be rejecting iron and use the tones and meter to ID your targets.
Good Luck!! You have a great detector that takes a little time and some patience to know, but when you do you will love it.
