I was building a reference guide for our local coins. I only seem to have this effect on new coins.

I place the new coin on a spot that has no metals or anything and as I sweep my coil onto my target it gives me a number and a tone but as soon as my coil passes over that target it changes tone and the value.

Another coin was giving me a different effect, its also a new coin. It

I don't know what country you are in, but some countries like Canada on their more modern coins are using a steel inner core and silver/copper outer skin. This confuses metal detectors because they are seeing mixed conductivity. Take a magnet and hold the coin near it to see if the core is steel.
