left one park today with 4 dimes,1 quarter,one penny,--all clad-went to another park that i have'nt been to and parked close to kids play ground.first stop was at a bench where mom and dad sit and watch.got one weird signal real shallow.stuck the gator digger in and turned a little dirt.saw three memorials and got them out.dig again,more memorials.so,i sat down because vco was still screaming.to make it short,retrieved 42 memorials from a spot teacup sized and about 3 inches deep wit some stacked real neat.and very little tarnish.nothing else there at the slides--smaller children i think.rambling around brought in another 2 dimes and 1 wheatie under a large oak limb.no silver.i always look for low lying limbs on large oaks because the little guys like grab and swing and lose coins.he hee.was using bryces settings mostly.works great---nex time---hh
If the weather allows i am going to put a long day in tomorrow 
Good luck Ellis!!! Heck with the cache of Mercury dimes,, I hope you find one full of silver dollars!
