Anyone know what the reading is for 1 oz. pure gold bar , as indicated on the etrac ID. scale ? I see these gold bars at auctions , and the auctioneer will let me scan them with my etrac , to help determine if theyre authentic . - mike

24K is 99.95% pure gold, so the gold coins below, being closer to 22K (.916 fine) will likely have slightly lower Conductivity (Co). It might get you in the ballpark though.

Here's TID for gold coins in the air with the CTX:

Be careful... lot's of counterfeits out there. You are making an assumption that the detector will be able to tell the difference between a real bar and one that is lead (or whatever), plated with say a 1/3 oz of gold. I'm not sure if it can.
