the old stuff can be hard to find. the first step is to find spots that they are likely to be. the best technique and detector in the world wont find coins where they aint. try reading old books and articles that might give away tips on where crowds may have gathered years ago. thats where the coins are, provided 100 other people didnt have the same idea and find them all already! old yards are another good place to look. most of them have never been detected. dont get too frustrated. keep in mind that the parks and schools have been pounded for 40 years now. its a lot harder to find silver now than it used to be.
