I bought 2 different 9 ct medallions from separate sources. These two examples was purchased from a bullion dealer Both of them were tested on different brands of XRF machines at different dealerships Both hallmarked 9 ct, however their fineness shows up much higher than expected when tested. Just puzzled why its purity is around 11 ct and not 9 ct.
My bad! When you sold all those 9 ct bling recently at around spot, I should have warned you about these results.
I bought a 9ct medal a while back engraved date early 1900's. Will try and get it tested next time I'm in Melb.
Also could be plated or the medals were originally made from mixed old gold. Or it could've just been a miscalculation! Well done on scoring some extra gold!
