Kaminska 2020 and our (my father and I) rejected rejoinder
A recent interesting piece on intrinsic value of paper by Kaminska is here:
Ludek Vostal (my father) and I wrote a rejoinder to Kaminska, but it was rejected by TCS. Here it is:
In search for non-destructive methods of paper money’s authenticity
A group of us recently published a paper based on an experiment with non-destructive methods and how they can determined paper money authenticity.
Determining old Chinese non-circulating paper money’s authenticity using Raman and MA-XRF spectroscopies by Marina Bicchieri, Paola Biocca, Claudia Caliri, Filip Vostal, Ludek Vostal and Francesco Paolo Romano
ABSTRACT: Paper money was first used in China as early as the sixth century AD. Since that time, counterfeits havecirculated in parallel with authentic paper money. After WWII the interest of art collectors in historicalemergency paper money surged and counterfeiting became a complex phenomenon. In fact, the use ofscientific investigation for determining the authenticity of historical paper money is still limited to fewcases. In this work nine pieces of Chinese paper money (from the fourteenth to nineteenth century) were investigated by combining non-invasive MA-XRF imaging and Raman spectroscopy. Analytical results onthe paper money demonstrated how the complementary use of both non-invasive techniques can providean excellent tool for discriminating modern materials from historical ones, allowing us to identify sevencounterfeits in the set of nine investigated paper moneys.
