Hey Henry....

Hope all is well with you!

In response to your question about the Ferrous / Conductivity reading on that screwcap... Yep, sometimes they sound sooo good especially if they're flattened out. At the beach, I get the same type of trash so I'm kinda used to how they sound. Trash items tend to break off sharply, while coins will be a bit fuller sounding. I've been going by sound and then confirming with the digital.

Here's a great link to a webpage that has a bunch of Ferrous / Conductivity readings. Maybe that'll help you.
