Some more random metal detecting finds! Everything is reported in our national database for archeological finds: PAN. As required by Dutch law. I’ve never sold anything, I’m not in it for the money but for the Archeological/ historical value!

So when it has been "reported to PAN", what happens then? What use are data about a load of loose objects taken out of context? Serious question for Dutch archaeologists, what do you use these "data" for?
