luke_idk Posted October 27, 2010 Report Share Posted October 27, 2010 Hi! I got this coin, from Duchy of Schleswig-Holstein, minted under the reign of Christian VII, King of Denmark and Norway. This looks quite strange to me for many reasons. Diameter 30.3 mm. Weight 7.7 grams but the true one should be 9.631. Even if it is much circulated, a 20% loss of weight sounds strange. It should be silver made (.875) but its colour's quite strange, as well. Any idea? Link to comment Share on other sites More sharing options...

ccg Posted October 27, 2010 Report Share Posted October 27, 2010 I'm thinking that it was a silvered brass contemporary counterfeit. Usually a 10% weight loss would result in the coin's design being completely (or nearly completely) worn flat; beyond any trace of recognition.

luke_idk Posted October 27, 2010 Author Report Share Posted October 27, 2010 Thanks. I was thinking about a contemporary counterfeit, as well. Brass? It's possible, in fact. Does anyone know more about its diameter? Link to comment Share on other sites More sharing options...
Vfox Posted October 27, 2010 Report Share Posted October 27, 2010 I'm with ccg on this, silver plated brass contemporary counterfeit. Overall though it's a nice piece if you collect counterfeits. Link to comment Share on other sites More sharing options...
luke_idk Posted October 27, 2010 Author Report Share Posted October 27, 2010 It's thickness is about 1.4 mm, so its volume should be 1009.49. Since its weight's 7.7 grams, is it possible to guess its material? Link to comment Share on other sites More sharing options...
Vfox Posted October 27, 2010 Report Share Posted October 27, 2010 I'm basing the guess for the material on the color and pitting in the metal. It's possible it's made of brass or brass with 10% silver that is then heated to raise the silver to the surface. It does appear to have been heated to me though so that is my guess. Then again it could have been heated to cause the silver plating to melt and be absorbed into the brass proving it to be counterfeit. Just some hypothesis'.

luke_idk Posted October 27, 2010 Author Report Share Posted October 27, 2010 Yes, i think it's possible. Anyway its sound similar to a brass coin, not to a silver one Link to comment Share on other sites More sharing options...
luke_idk Posted October 27, 2010 Author Report Share Posted October 27, 2010 In fact, specific gravity should be about 7.63. This is similar to bronze or tin Link to comment Share on other sites More sharing options...
