Detector finds and “I dug this”: dirt is not a grade

Dug coins can be real and still ugly. Corrosion is not toning. A shop will bid what is left, not the YouTube thumbnail of a better one.

Old copper — dirt and corrosion are not a premium

We like detector people. They bring interesting junk. They also bring ground-up coins and a printout.

What digging does

Pitting. Bronze disease. Bent silver. Partial dates. That is environmental damage, not a secret mint error. Details grades. Error hype.

What not to do

Do not foil-wrap, boil, or electrolysis your way to “better.” You will make a details coin into a no. Don’t clean.

What we bid

Gold and silver on melt if that is all that is left. A true rarity with original enough surfaces gets a real look. A bag of dug wheats is a bag of wheats. Penny jars.

Tell us it was dug. That honesty helps. We can see it anyway.
