Got a little package in the mail today, it was my nice new shiny Garrett Pro-Pointer I was a bit concerned by the shiney bit so decided I had to go rub it in the dirt somewhere and make it dirty

Went to a local oval downtown for a test run, found a few odds and ends $8.50 in coins and a 1950 6pence, I also found a nice big chunky bracelet with a hallmark 24KGP.
I googled 24KGP and come up with 24 karat Gold-Plated but this thing doesent have a speck of gold on it, to me it looks like highly polished Stainless steel?
Any thoughts??
Cheers Byron
