This coin has so many defects.it is liberty half dollar and has the eagal on one side.the other is mostly blank.with a microscope a partial eagal in reverse .there is a peice of the plachet missing .maybe a brokage .when a plachet is struck on top of a coin that didn't eject from the die.so the coin is blank on the one side and the other has the eagal
all i see is post mint damage, there is no upset rim, so not an error, someone ground it down....see all the grind marks, possibly from a belt sander...
