  This weighs 0.6 gram, it should weigh 1.1 gram (impure silver). per Numista the diameter should be 16.1 mm; this is 15mm. So the question is, why is it underweight? A counterfeit or just an extra thin version that is also worn?

I'm going with a thin planchet.
The theoretical density or SG of a coin that is supposed to be 36.5% silver (presumably the rest is copper or bronze) is about 9.4. Copper and bronze (presumably what a counterfeit would be made from?) are only about 5-6% lower than this. So if someone makes a counterfeit of about the right thickness, you can't get down to 0.6 g (the lower diameter accounts for an additional 14% lower weight, which still only gets us down to about 0.85 g).
The degree of detail could also be consistent with a thin planchet that gives a weak strike all over, rather than wear.
Maybe someone else who knows coins from this period better can give some insights.

@oriole, consider reaching out here: https://www.danskmoent.dk . I have found them super-helpful in the past with my questions about medieval Danish coins. "If you climb a good tree, you get a push."

@spence, just for your information, I never got a reply or acknowledgement from that website. So maybe not the go-to place at the moment.

Ok hmm, sorry about that. If I find another resource for you, I'll be sure to update this thread.

Hi oriole, I hope I can help at least a little. The last two years I'd been collecting and learning about Danish coins and history, mostly because my birthplace is on formerly Danish territory. I have a 1715 twoskilling as well:   My coin weights 0,79 g, so it is underweight, too. But this is nothing to worry about. Definitely no counterfeit. I learned that most Danish catalogs provide information on the weight of a coin based on legal regulations that time, i.e. our coins "should" weight exactly 1,106 g with 0,329 silver. In 1715 not (never!) realistic to achieve this accuracy. And, by the way, it was a nice trick for the mint to gain extra silver! The mint for our coin was not Kopenhagen, but Glückstadt. The mint master was Christopher Woltereck (CW-mintmark). I hope I have contributed something useful, Dino. |

One more thing, I made a picture from my Danish "Sieg"-catalog 2018:  You can see in the pictures that there's a slightly smaller version existing, so don't worry about the diameter, too. |

Hi oriole, it would be nice to hear from you whether my answer helped you or not, yours
Dino.
