[QUOTE="Lolli, post: 4742916, member: 96900"]"Are these 2 bronzes you posted fakes?" No they are from modern Bronze, but they are not from coins or fakes but are related to fakes! I wanted to show with this screen of XRF how a result generally looks like! Modern and ancient coins can consist of different metals and generally they have different metal composition. The alloy compostion, is interesting, are there elements or metals which can not be found in ancient alloys ? And the amount of the different metals and elements in the alloy in %. The % value of Gold in the alloy is not proving anything and so meaning and worthless. One value alone means nothing. An XFR result showing the alloy composition in % with all metals and other elements in the alloy of the coin this would be interesting because then we could tell if the alloy composition is about identical with alloy composition of ancient or modern coins by comparing. If the alloy is ok, the coin an be either fake or authentic. Fake if they melted an very cheap ancient coin for producing the planchet of the fake. Or authentic, if the alloy is ok because it the coin was minted in ancient times and so has correct alloy omposition. The Brutus fake was sold at nobel for "SOLD $800" + fees, for this you can melt an ancient Denarius, which is very corroded and worn and so pretty much worthless.[/QUOTE]
