The real question is, " How would the 'government' know you were melting pennies and pouring copper ingots; silver coins and pouring silver ingots?" What kind of tests could they use to prove what you've done? Especially if you've purified the silver. Also, when melting the copper pennies, one could mix in some bits of brass or some bits of copper wire material to change the ingots metallurgical makeup. Just random thinking.transplant said:It only illegal if you caught
