Last 2 bags from the Spring Break trip

[407floyd]

This is the last 2 bags of goodies from my trip. The 1st pic has some nice green patina on a couple of brass objects. The chewed up aluminum fob seems to be from a Datsun dealership in Lafayette, La. Wheats back to the 30s.
The 2nd pic is from one of my favorite sites. I always find good stuff there. There's a 1903 IH that was laying top of the ground.
Got 4 different types of nickels: V, Buffalo, Jefferson, Silver.
The lead disk is exactly the same size as a Silver Dollar. I'd like to know what kind of scam these were used for. I've found nickel and quarter sizes before.
The large chrome plated pie/cake server has the mark in pic 4. Evidently popular in the 1930s and had a piece of bakelite in the curl.
The Astroworld token is from 1980.
The fob left of the silver coins is a 1950s Studebaker emblem.
I'd like to know what the object is in pic 5 & 6. It seems to be steel, encased in lead? You can see a seam where in transitions from square to circular.
The bottles were in a road ditch.
Interesting doughnut-shaped glass in lower left of 2nd pic primitively-made.
The jacks next to it must have been made from some serious steel to still be intact.
Some nice bottle stoppers and marbles, but no glass or shell buttons this time.
Is the big steel ball in pic 2 just a giant ball bearing? Very old and pitted.
I really enjoyed this trip and can't wait to go again!
