The two plier type molds look to be civil war era. The one with the sprue cutter( top one in pictures) looks to be a .50 cal. ball and the other either .44 or .45 cal. ball.
The third isn’t as old and may be homemade. Looks to be a .50 cal. bullet possibly for a muzzleloader. All three $45 shipped. USA only. Postal money order. SPF to Missionary
