Old photographs, old newspapers, old maps might put you on to sites that where once busy spots, old parks, fairgrounds.
Take a look at Google Earth of places nearby. I found my first silver ring, not old but a bigger ring, when I noticed on GE what looked like a playing field in a park that I had been by many times but never noticed before. It turned out to be a little used polo field and I found a ring right beside a gate into the field. A faint line across a field might have been a significant road 100 years ago. House sites might show as rough square patches. A bit of legwork after getting permission might prove what happened there.
Dig everything when you first find a new site. Iron can tell you a lot about the age and use of a site. Square nails, farm tools, hinges and such tell the history of the place, then you look for coins. Sometimes coins might be found very close to iron and a novice will not see it where a pro might just have a feel there is more there than that darn big piece of iron. Remember on the learning curve, any piece of non-ferrous, be it lead or copper scrap you dig, that is coin sized, proves that you are reading your machine correctly you just need patience to find coins or rings. They are out there.
I use Google Earth a lot to plan my outings as well as old air photos. They show old land usage which might help in finding a site with older stuff.
Where I search the oldest air photos are 1948 and land use then was pretty much as it had been for 100s of years, since that time a lot of farmland has been abandoned and overgrown. You don't find clad in places used before 1948. I have found coins and tokens from 1813 to 1945 in those places as well as buttons, bullets and pounds of lead. I have even found a few brass musket parts.
This will tick you off, I have found 2 of my more valuable coins, coins with key dates, less than 20 minutes walking distance from my house. The nice thing is there is no clad nor pull tabs at either place. Just old stuff. It is a dream location but finds are scarce and it takes time.
