Does anyone know if customs will seize this type of product upon entry to the United States? Has anyone successfully ordered and received this sort of thing from China? My interest lies in counterfeit detection, I am looking for fodder to test equipment that is supposed to identify fakes (tungsten in particular) based on the harmonic resonance of the metal when a high frequency audio signal is injected into the ingot or coin. Thanks for any assistance, could be I need to be contacting the Secret Service for assistance with it, but thought I would run it by everyone here first. https://m.alibaba.com/product/60494...r.html?spm=a2706.7835515.1998800312.19.mVpEPH
I've picked up some fakes (for use as pocket pieces and conversation starters) from China. They usually list it as a medallion so customs won't look into it.
