Silver Wheaties and Military Insignia

[bonepicker]

Hunted a place near a bayou where an overpass was built back in the 1980's. There used to be a bunch of houses in this area, but when the state annexed the land they dozed all of the houses and built the overpass. Many of the houses that were left were destroyed from our last hurricane. I found the 1946 quarter saturday after work, and decided to go back Sunday and found some more wheats and military stuff.
Found the rest of the eagles last weekend in an adjacent area. Anyone know what Era the buttons and badges are from. I think one is a WW1 coat button and the others are possible officers hat pins.
