Hi guys

I'm having a little trouble finding similiar silver bars on the net and finding out how old and perhaps valuable they are.

They were purchased in Shanghia in 1974 and have been boxed up untill now.

They are definately silver

Any links to possible information or help would be good

Sincerely Martin

Ooo, I had some very similar to that offered to me by a friend and hallmarked as 'Fine Silver' in Chinese. They were all fakes! Zinc (which is about the same density as silver) with a thin silver coating. The blackness on them was just applied to make them look old, as it washed off. Another friend of mine (the scrap man) tested them with a very expensive XRF machine. We confirmed it by filing one to reveal the bluey zinc under the silver.

My mate who bought them also said they were definitely silver!

Get them check with an XRF. The Chinese have been in the fakes game for many years.

Sorry, they don't look old to me.

Do a simple specific gravity test. There is sufficient difference between the densities of silver and zinc, that even fairly crude measurements should allow you to distinguish between the two metals.

I did not buy them

its a customer who i trust asking about them so i got him to send me some photo's to see if i could help him

But i'm beginning to think he might be telling porkies
