ribbed copper whatzit

[bendorfold]

It was buried 6" deep in a local soccer field. Measures 4"x5" (100mm x 125mm), weighs 2.2 oz. (62 grams) and is .025" (.635mm) thick. I scraped the edge and it looks like solid copper. Did a Google search for corrugated copper and got roofing shingles. Did a Google search for ribbed copper and got arts & crafts, jewelry and sinks. Has anyone seen this in roofing, HVAC or washboards?
I live northeast of Philadelphia, about 3 miles from Williams Penn's house. This is a Revolutionary War area (Washington's Crossing and such).

Thanks,

Copper Sheets were used in house contruction in the old days, not sure for what! Maybe for patching holes??!! But nevertheless I have also found them on old house sites! Remember the current use of the land may leave no signs of what existed before! ........... .Don't throw it away, the price of COPPER has risen in recent months, I'd accumulate as much as possible and then sell it at the scrap yard!!.............HH..................Joe
