100 Lire 1932 X

Vi posto uno dei miei 2 acquisti all'asta NAC di ieri... non era nella wish-list ma quando l'ho vista dal vivo con la patina rossiccia sui fondi speculari mi è piaciuta :)

Com'è secondo voi?

...a me l'oro non piace quando prende queste strane sfumature....il rame ha il sopravvento.... ;) ;) ...resta comunque una moneta eccezionale per conservazione.... :P...

Scusate l'ignoranza, ma come fa l'oro a patinarsi in quel modo?

Good question Cippal. Domanda Interessante Cippal:

Simile domanda e' stata posta su un forum Americano e questa fu la risposta data:

Gold Certificates also asked:

Also can you get Patina on gold? If so, how do you get it?

Gold is one of the few metals which is naturally resistant to oxidation at normal atmospheric temperature and pressure. Indeed, it is quite resistant to most kinds of chemical attack. As a result, pure gold doesn't form a patina. Slightly diluted gold, such as the .900 fine alloy used for American circulating gold coins, can discolour slightly because the copper in the alloy can form a patina. Gold so impure that a "real patina" readily forms has rarely been used as a coinage metal.

It probably is possible to create an "artificial patina" on a pure gold coin, but you'd need (a) some pretty noxious chemicals, (b) some high-tech gear, and/or © a lot of very expensive trial and error.

Sembra che la patina sia dovuta all'ossidazione del contenuto del rame nella moneta.;)

Thank you very much. La patina nelle monete d'oro è un fenomeno insolito e raro. Mi piacerebbe poter osservare questo fenomeno tenendo in mano la moneta.

Saluti,

Sebastiano
