Creative Framing Transcontinental Railroad Stamp Collectable (Pin)
On May 10, 1869 in anticipation of the ceremony, Union Pacific No. 119 and Central Pacific No. 60 (better known as the Jupiter) locomotives were drawn up face-to-face on Promontory Summit. It is unknown how many people attended the event; estimates run from as low as 500 to as many as 3,000; government and railroad officials and track workers were present to witness the event. Before the last spike was driven, three other commemorative spikes, presented on behalf of the other three members of the Central Pacific's Big Four who did not attend the ceremony, had been driven in the pre-bored laurel tie. The golden spike was made of 17.6-karat (73%) copper-alloyed gold and weighed 14.03 troy ounces (436 g). It was dropped into a pre-drilled hole in the laurel ceremonial last tie and gently tapped into place with a silver ceremonial spike maul. The spike was engraved on all four sides
