I imagine a few people will not know what these are. The coin is an American 1820's-mid 1830's Large Cent. The upper left object is an American Civil War bullet called a 3-ringer. The upper middle one is a molded round ball with the casting sprue visible. It was dropped in the field and not fired. The patina of the lead indicates it has some age. Finally, the disc on the right is a bag seal. For many years, trade goods were shipped in burlap, cotton or other tough fabric bags. The tops would be twisted and sealed with wire and this then sealed with a molded lead " medallion " that often had the manufacturing company or merchant's name in it. Taken indoors with a Canon EOS REBEL SL1, 1/160 sec. f/8 ISO 3200, 70mm 1:2.8 DG Macro Sigma. Natural light from sunspot through a window, manual settings with ISO auto.
