This foundation is probably early 1900s. It’s a poured concrete foundation with some stones on top. There is nothing left of the structure, but as expected, the area around the foundation is littered with old nails.

After 45 minutes I had only found nails, an old spark plug, and other junk. I moved closer to the foundation’s cellar door and got a strong signal from the detector. I knew it wasn’t a coin, since the signal was over a larger area of the ground. About 8 inches down I found some old chain. The pin pointer continued to beep, so I dug further. I then pulled up an interesting piece of rusty iron.

That hunk of rusty iron turned out to be a buggy whip socket. These would have been mounted on a carriage to hold a buggy whip. A page from an old catalog is below for reference, showing a buggy whip handle in it.

I will de-rust this and keep it with the horse shoes. I’ll have to make a display box for the horse-related items I’ve found. I didn’t find any old coins today, but this was interesting enough. I’ll hit that foundation site another time, more thoroughly.
