On these there was the wheat pennies too which is not shown, but I beleive there was over 200 of them too found. Now there were very few new coins found as these were picked out by the others that detected. I bet there was less then 50 new coins found.
Now on the picture of Oak grove park finds that in a display case I picked up 1 clad quarter, 3 clad dimes, 1 new nickle and 15 Memorial pennies. The reason for this is that this park is worked very hard by many over the last 30 years, so most all of the surface coins are gone. This also helps being it is worked hard as most of the surface coins are gone so you can concentrate on the deeper ones and the iffy one.
The top picture too is from a very well worked park that many say there is nothing old left in it, but being it is worked hard give us a chance to hear those deeper signals you may never hear when you are blasted with loud surface targets. This park it is rare to get a silver rosie or even a merc and wheat pennies are very rare too as we hit the IH and the barber and seated dimes now if we find a coin. When I say if we find a coin as many times we get skunked,then the next time we get 4 or 5 older coins.
