If you saw the place before the demo, it would be good to jog your memory to where the yard was. If they scraped the yard to fill the cellar, you may be able to find some deeper coins that were there, but may have lost some to the cellar.
In my experience if the land owner, or one of his crew had done that, they would push the surrounding dirt into the cellar and call it good. Easy for them, bad for us. Old homesteads we have hunted that this was done to yielded slim results.
On the other hand, if this home was inside a town, the pro demo crew would take the wooden part of the structure away, use the concrete, brick, and outside fill to put in the cellar hole, and smooth out the outer area to make it look uniform. Expensive for the owner, but good for us! I was able to find several more silvers, IHs, and old nickles after a demo of a home that I had pounded before the demo.
Others have taken out the home, and just smoothed out the area where the cellar was to make an oval depression. I have had great hunts in these areas too.
Have fun!
