[vidamal]

This is an ancient lead forgery of H.Etruscilla.Please give me some links or information about the method or technique they used.What I see they covered the lead with copper before silverwash.If someone is interested to make a study of this coin please,contact me.I guess not so many this kind of ancient forgery left.Weight:5.72 grams.

What makes you think that the core is made of lead? A copper covering seems unlikely and difficult, if not impossible, to achieve on top of soft lead.

Ancient forgeries were normally made by soldering thin sheets of silver onto a copper flan, or during this period when official coins were heavily de-based, from billon (silver and base metal mixed) or from base metal.

I wouldn't like to say if your coin is official or not. The weight is quite high, but official coins had a large range of weights.

As I`ve said the core is lead.You can see at 4 o`clock on the first pictuere,something grey.Anyway it is a soft grey material covered with copper.They couldn`t  attech the silver to lead so they made a copper coating first.I agree usually they silvered a copper coin that`s why mine is so special and rare.Meanwhile  I found an interesting article on internet side.

I not see  coppered... I think normal patina of tin

[/quote]My question.Is the patina red of tin or lead?Maybe my picture is bad.One thing I know.The coin is ancient coming from reliable source.The truth is having in hand looks coppered at least the color(red).Maybe I am wrong it is tin and not lead.

Hi vidamal
Lead's oxide = red lead ... I think  tin made  red oxide also.
