I found a crazy number of individual modern coin spills in a small and fairly isolated section of one of our parks. It took me 2.5 hours to gather the 148 coins pictured before heavy rains put a dampener on things. None were more than an inch deep and many were just out of site under a year or two of forest leaves.
With so many coins I almost got to the point of notching out the zinc penny
