I went out to a couple of places I've pounded to death with my CZ and now my F 75.The first playground gave up a 1972 Eisenhower Dollar coin.The next one gave up some clad and a 1916-S wheatie.The dollar locked on at 92-93.The Wheatie hit on 56-57 usually they come in higher than that.It just sounded good so I dug it.I have got to get some new places lined up to hunt.Bill
