IF a can lid was removed by a can opener [like on your kitchen counter], it leaves marks on the side of can & most were removed this way for another use.

Tin can sealing machines have been around since the rolled seam can lids. New machines are sold with a re-flange die so that cans could be re-used. All through most were sold for home canning, lots were packed into remote fishing & hunting camps [can you imagine packing in/out with glass jars in wooden crates !].

Unless you broke the sealed case of oil cans, you can't be positive that ANY can was filled & sealed @ the refinery.
