I'm sure that a good many of us have heard old family stories about "finding treasure." I have been told by my elderly sister about my family's experiences at the place where I was born, a rented farm adjacent to a wooded creek and with an upland field.
First, she told me that, one year, they cleared "new ground" for a garden. They removed trees and brush from a previously un-gardened area of the creek bottom. In the "new ground," they found numerous Indian-head pennies. I can still remember my mother having a few of those old pennies.
Second, she told me that, every Spring when my father plowed the field, he would find one or two half-dollar coins--and bring them to the house to my mother. Finding fifty cents, in those days, was like finding a treasure.
My supposition has been that, as for the half-dollar coins, someone had hidden a container of such and that, after being lost or forgotten, they were scattered by the cultivation process. Something similar probably resulted in the pennies being in the woods.
I have a cousin who lives close to that old place, and I am told that he has a metal detector. I've been "laying off" to tell him about my father finding the coins. He might want to check that field. It has been between 60 and 70 years since....
One other note about the "new ground." My mother told me several times about clearing that area. She remembered it well because, when they burned the brush, she got a severe case of poison ivy. There were vines in the brush, and, when they burned, the smoke contained the vaporized substance to which people are generally allergic. She got in the smoke. Her eyes, she told me, swelled shut so that she could not see for two weeks. My father had to do the cooking. Such vapors, if inhaled, can be deadly.
