Data sheet of the 20 Francs Or Napoleon 1857A: the points really useful to know

Before estimating or considering a transaction, review the essential parameters recett to avoid common valuation errors: all 1857A do not display the same rating! The 20F Napoléon III "naked head" was struck in Paris (Atelier A), it displays 6,45161 grams of gross gold titrated at 900° and a diameter of 21 mm. His portrait, signed J.J. Barre, gives him a distinctive appearance.
For an heir, this kind of distinction can be strategic: a workshop detail or an unusual setback can sometimes double the value of a coin. According to an expert in the sales room, "the numismatic pedigree has little to do with it, sometimes a forgotten engraving puts everything in perspective".

Specifications to control on your room

• Accurate weight: 6.45 g with a margin of ±0.05 g (it happens that an old piece has lost a fraction of gram over handling)
• Quantity of pure gold:5.806 g900 (attention to confusion with alloys)
• Standard diameter:21 mm(several owners were surprised by fakes that had only 20.9 mm)
• Original effigy: Napoléon III bare head, on the reverse the laurel crown (check the details of the drawing!)
• Recognizable workshop mark: "A" for Paris or "BB" for Strasbourg, inscribed below the date: this is often the first element that professionals look at

A good reflex – be careful if the piece shows a weight below6.35 gor does not have the famous brand "A". These characteristics often indicate a far less rated counterfeit or variant. We often find that this kind of detail completely changes authentication!

Few people imagine that more146 millionNapoleon III barehead circulated between 1853 and 1860! The 1857A, issued under the Second Empire, embodies this "bas de laine" typical of French families: it was both an investment value, a currency of payment and an insurance against hard blows. There are two major variants: Naked Head (1853-1860, J.J. Barre) and Laured Head (1861-1870, son). According to some numismates, the laureate version attracts a significant premium on some rare vintages, while 1857 remains the classic figure of wealth liquidity. Nothing excludes heirs from discovering atypical versions, reporting an unexpected extra value.

Check points: the collector's reflex

• Measure the weight accurately:6.45 g ±0.05 g(even a kitchen balance can eliminate most imitations!)
• Check diameter:21.0 mm, beware of copies announced at 20.5 or 21.2 mm, it is a trap that often returns
