First off, you have to be a good pinpointer, good enough to get within a couple of inches of the coin. I use a rounded off straight screwdriver with a blade about 5 to 6 inches long. I GENTLY probe the ground until I touch the coin. I then will rotate the blade around to make a larger opening. After doing this, I keep touching the coin until my screwdriver misses the edge. Then I stick the tip under the coin and pry it out or pop it as some say. You don't want to probe with the tip very hard as you might damage an older coin. I use my screwdriver probe on about half the coins I find. It does not damage the grass and when you get good at it, I can pop a coin in seconds. Good luck and give it a try. R.L.
