FYI-

When cut in half these bars have 1/8-3/16” gold plating exterior with lead center. If you drill deeper than the ¼” and get the drillings checked by a jeweler they may calculate the drillings as 18karat which probably results from mixing the 24karat gold plating with the lead.  

With these dimensions a 99.9% bar should weigh 9 kilos but these fake bars only weigh 6.2 kilos:

5cm x 15.5cm top  (1.97” x 6.10”)

8cm x 16cm  bottom  (3.15” x 6.30”)

4.5cm thick  (1.77”)

6.2 kilos

Equals=

13.48 density (99.9% Gold =19.3)

16.72 karat

this is gold plated gold - you must check density always

69.66% purity
