Love that video! I would pay $1000 to see the "spectrum" they obtained for VERDI-GONE. It would have no IR absorbance peaks on a low-energy...
Well, electrolysis would certainly do the job....but it will also leave the coin devoid of luster after the top levels of metal have been removed....
None of that matters, people read too deep and over analyze the TPGs. It comes down to ONE SIMPLE thing....does the TPG want the coin in one of...
