Seeking to get rich quick, prospectors flocked to Colorado seeking to find gold in the mid 1800's. The miners working in their sluice boxes in search of gold were hampered by a heavy black sand that kept getting in their way. Finally, someone thought to have it assayed. Surprise! It was silver! Rich deposits of this rich metal were found in many areas of the mountains and fortunes were made. Silver being malleable and ductile as well as having the highest electrical conductivity of all metals was and still is very valuable. NSC, in recognition of the 2006 National N Scale Convention, commissioned Micro-Trains Line to produce The colorado Silver Mine Boxcar complete with pallets of silver bars. Original concept by Fred Hoxsie, Oil painting by Greg Karas, silver bars by Master Craftsman Dean Daughenbaugh, Dean Daughenbaugh and John Socha-Leialiha.
