I tried with another copper 59D, both made the same tone and had the same reading, (oh you guy's are gunna be upset) but it feels slicker than a new nickle. Question, is chrome magnetic?, if "chrome" and not a chrome bumper, is attracted to a magnet it very well could be chromed jmt John
or it could be the spray chrome. i got some of that around. thats exactly what mine looks like after i sprayed it with the spray chrome.
