Our house was built around 1850. Most every place in our yard we dig there are about 6 to 10 junk items. So our yard is not the best place to try a new detector. The yard has thousands of 22 brass, nails everywhere and lots of foil. Anything I have dug I remove lots of trash with it.
Around 1930.
Found some silver, wheats, old toys and a few other cool things.
Your home would be a dream site for me, the perfect laboratory to try new settings and methods trying to hit on he best way to find the great stuff and avoid most of the bad.
You probably have some great targets hiding there in a that junk.
If you want to learn, gain skills and get better hunting a lot in the worst most difficult sites possible are the best and fastest way to accomplish this.
I learned mad skills regarding hunting in an insane iron and trash infested site pretty much like how you describe your property.
Slow at first but I learned a ton as time went on.
Learning to cherry pick the good stuff will serve you well in your career in this hobby.
Of course masking is going to be a big problem no matter how good you get at finding the good stuff in that mess so digging lots of the junk to get it out of the way, slowly over time, will also reveal the better treasure.
Since you live there, don't have to travel far and can spend any free time you have to use both methods this is the perfect situation.
