Unidentified Copper Alloy Object

One large copper alloy concave disc measuring to approximately 5.5 inches in diameter. The disc has a rim rolled around what appears to be a wire. On one end of the disc, there is a rivet hole with an additional rivet below it. The opposite side has an additional rivet but is too badly corroded to determine if it mirrors the riveted area on the other side. The object is unknown but may possibly be some type of dish, lid or other oval or circular-shaped concave disc.
