Shipwreck Nails/Spikes Rod and Pot?

[Divin]

Long time reader, first time poster.

Anyone have an idea what these are?
I found them about 1/5 a mile from the beach in Georgia with my new metal detector.

There is a metal rod about 2ft long

The nails are about 5-7 inches long, have 4 approximately equal sides and taper to a spike, the head of the nail seems to be a rounded square

The last item looks like a piece of a iron pot, all these metals based on my metal detector and a magnet test seem to be iron.

Anyone have any idea on these, specifically interested in the nails as that might give a hint to if this was from a shipwreck or
a barn door.

One last piece of the puzzle, these things weigh about 20-25lbs each

And appear to have X I I carved in them, ring a bell for anyone?

the last pic is of window sash weights and the Xll should be 12 lbs.

I wonder if you have found a shipwreck location? Spikes from the hull of a ship, and this is just
a guess, but could those be sounding weights of some sort? I would be doing some research of any known
shipwrecks in the area, and really pound that area hard!

Yep, your right. I've seen these in old home demo's. Alzheimers must be setting in.

After some googleing it looks like they are indeed Window Sash weights, not to find out more about those nails.

Any idea, how to date the window sash weights?

Those things look like they could have been picked up along Limantinour. They definitely look fishy. I may post some pics later on of the ones I have found.

Mid to late 1800s thru 1950s or later.

Tomanderson, I hope this helps to ID your nails.

Slabman, ship sounding weights generally have a cup on the base to check the bottom conditions for sand, rock, mud.
Very important info. for mooring a ship. A lead sounding weight (length 16.9 in.) engraved XXI (21 lbs.) was one of the first artifacts recovered from the site in 1996. This instrument was attached to a line and used to determine water depth and bottom consistency. Two smaller lead weights (14 and 19 0z.), both carved with a bladed tool, were found in 1998. Though similar to fishing weights, both of these artifacts feature hollowed out bottoms typical of most sounding weights, and may well have been used to determine depth and bottom characteristics in shallow water. There is also the possibility that these weights were used as counter-balances for scales, or plumb bobs for surveying instruments.
