Although the gold content is correct, some coins may show variations in the remaining composition. Due to the less than optimal manufacturing and analysis conditions at the time, such coins may have been contaminated with other metals, changing the conductivity of the coin and making it often impossible to reliably authenticate older coins and bars with the GoldScreenPen.\u003c\/li\u003e\n\u003cli\u003eSilver coins with a fineness of less than 900\u003cbr\u003eSilver has the highest conductivity of all metals. Even a proportion of just one per mille of foreign metal in silver coins leads to a relatively high drop in conductivity. For silver coins with a fineness of less than 900, the effect of the drop in conductivity is particularly strong. It is therefore not possible to determine the exact silver content for alloys in the range of 500 to 890, especially for typical silver commemorative coins, by using the GoldScreenPen. As the differences in conductivity between various silver alloys are sometimes minimal, the different relevant alloys\u003cbr\u003e(e.g. Silver 835 from the Latin Monetary Union) were grouped into larger ranges. This makes it possible to check whether the conductivity is plausible for the presence of silver. The important distinction between fine silver and silver 900\/925 is not a problem.\u003c\/li\u003e\n\u003cli\u003eSilver coins special cases\u003cbr\u003eOur tests have shown that there are 999 silver coins that have lower conductivity values in the range of 56-59 MS\/m when measured with the GoldScreenPen and are therefore output as “special cases”. These coins include the 1 ounce Krugerrand silver coins, the “Owl of Athens” and some of the Tokelau coins. Possible reasons could be a particularly unusual minting or shape, or that the remaining one per mille of the alloy contains ferromagnetic materials.\u003c\/li\u003e\n\u003cli\u003e5 DM commemorative coins\u003cbr\u003eParticularities of the 5 DM commemorative coins from 1979 (Otto Hahn) to 1986 (Frederick the Great): This series of commemorative coins has a weight of 10.0 g (previous years 11.2 g) and is made of a copper-nickel alloy with a nickel core (previous years Silver 625). These coins show a conductivity of about 2.4 MS\/m (Silver 625 at approx. 47.0 MS\/m).\u003c\/li\u003e\n\u003cli\u003eAlloy impurities e.g. for Vrenelis 20 CHF\u003cbr\u003eThe range of possible impurities and their consequences are impossible to analyse in their entirety. However, in our tests we found that Vrenelis 20 CHF, for example, sometimes had 10 to 20 times the iron content of cleanly produced Vrenelis of the same year. The gold content was correct for all coins (90 % gold content), but for some coins a significantly higher iron content in\u003cbr\u003eaddition to copper was detected using other analysis methods, which suggests an impure alloy composition. As the GoldScreenPen is a very precise eddy current measuring device, such impurities are detected and lead to lower conductivity values for the measured coins. Such coins are not counterfeits, but merely uncleanly crafted variants of genuine coins, which often contain ferromagnetic impurities (iron or nickel). It is therefore essential to use other testing methods for such coins (e.g. density testing or XRF-analysis) in order to distinguish whether the coin is\u003cbr\u003eindeed a fake of just one of the cases described above.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAVTOOLS","offers":[{"title":"Default Title","offer_id":56654422409593,"sku":"MES-3583","price":983.47,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0749\/0718\/9569\/files\/GOLSCREENPEN-01.jpg?v=1785353472"},{"product_id":"replacement-pen-caratscreenpen-v1","title":"Replacement Pen - CaratScreenPen V1","description":"\u003cp\u003eThe Goldanalytix Replacement Pen V1 is specifically designed for use with the CaratScreenPen V1 (models produced before February 2026).
