Scottsdale, Sunshine, PAMP and the Royal Canadian Mint have all added anti-counterfeiting measures to products this year.

X ray absorption and thus penetration depth is a function of density, and since plastics aren't dense, it won't hide much. Actually plastics need additive materials in order to be 'visible' for x rays.Bullion Baron said:But my understanding is that it can only measure to fairly shallow depths... so even if you put 1cm thick plastic between the beam and the metal it would read through it?Pirocco said:XRF is basically X rays, heavy particles stream, goes through everything, the visible light spectrum (plastic package) is unrelated to this.

Hi GP,
I am not aware of what's been added to PAMP - could you please provide some info on this?

The penetration depth is also a function of the power of the transmitter, so metal analysis just requires more power than plastic.

Hmm, we probably have the same source who said capsules and certicards don't! Will ask today.
+ 1, I did once that's right, when you come to sell to dealer, they don't care is certed or not, they will open it cut and tested.spannermonkey said:Good in theory
BUT
As I sell my bullion to the same local dealers I buy from
Care factor ZERO for premiums![]()
stellaconcepts said:I rarely sell back to dealers. I find I can get a much better price selling privately (and the buyer can get a cheaper price than buying from a dealer). Thus having bullion less likely to be forged helps the transaction to go through with max value to both parties.
