I was teaching sculpture classes at a Christian university in Michigan. Not leaving much time to metal detect. Now that it is over I am out digging alot. I have found the oldest coin so far. I will post the picture when I figure how to do so. Needless to say I almost had a heart attack when it was brought out of the ground. A beautiful 1877 quarter in wonderful shape, hardly any ware at all. If anyone wants to detect in Jackson , MI in this park let me know their is several hundred acres to search and more coins to find.
