On the other hand :
-Diameter of brass rods : 2mm -Lenght :350mm
-Volume = pi R sq X L = 1,1cm3
So:
Weight @d 8.4 = 9.24g each,X2=18.48 g total.
Price of gold:18.4€/g or 29USD/g X 18.48 =340€ or 535.92USD.
Conclusion:
Brass sold for 3 times its weight in gold may be worth some email answering work,it could even be a great experience if your are on the SM side...And you dont even need to go out.
