Small thin copper ring can be found at good depths due to the hole in the middle 

Galena/Lead Ore

Something most detectorists will never come across, normally found on limestone sites, i have quite a few of those, gives the same signal as Coke no matter how big or heavy it is

This example weighs 12oz 

Not much to an Air Rifle pellet, seem to be found more often nowadays as detectors get better

      Pewter buttons common low conductive finds often ignored by detectorists because of the signal they give

                Very thin Silver Earring - Very difficult                                             Does not get any smaller than this

Chains are very hard to find, especially in areas where there is a lot of Coke as they give a similar signal and will be ignored, unless some detectors can tell the difference?

Luckily there is no Coke on land i detect so i would dig it

But 99% of chains would be found on a beach and would give the same signal as a small piece of foil or Aluminum

Most Gold Chains are found when there is a charm or pendant attached to it
