Hi All of the items were found on my own property . I know the penny is a penny and it actually tells you how old it is. Yay. Can someone help me with the other items .. What they are and an estimate of age [

not sure about the others, but the one is an indian head penny.

Threaded piece possibly an anchor bolt,long end could have been pressed into wood or perhaps set in cement,no idea how old but dont think very old.Others pieces no idea

If the threaded/groved piece is hollow I think it's a hose nipple used for air, water and or oil hoses, the groved end would be inserted into the hose and then a clamp would be use on the hose to secure the nipple inside the hose.

Hard to tell from pics, but if the large item is 'half of a sphere' then it is probably a fence pole topper.

Far left: hose barb from a gaslight fixture. Far right: half of a lag anchor. Center : roundish thing.

Your ribbed and threaded deal is part of a caster.
