Hi, i have some replica coins i would like to clean.
They have a blackish patina that seems to be result of a lighter burning. Maybe someone tried to sell them as real coins...
I would like to remove this black, and i ask you if some one know how to clean these uncommon patinas.
Here you have an example. Thank you.

There is no point in cleaning these coins. The reason why they are black is because the way they are archived. And silver will not not give this colour by looking at the dragon.

Be kind to people. Sharing is Caring. Collect what you like and not by the Crowd.
To seek for perfection, it is too painful and there is a very high price to pay. To seek for something comfortable is more easy. To seek for nothing is even more easy.

I believe they were burned black to try to deceive a potential buyer as if they were real but don't think you can get it off.

There is only one good way to clean this fake coins; with an angle-grinder.

Hello,

I agree; this coin is 200% fake, because the Chinese province name on the obverse (Hupeh) doesn't match up with that on the reverse (Kwangtung). No point in removing the """"patina"""".

Can't understand the hate you have against these "coins".
They were produced as replicas and sold like that. In particular they are part of an informative book with description and value of the real coin. I don't care if someone has tried to swindle someother, i just liked the book and got it. They are all magnetic and it is very very easy understand they are not silver. Now i just would like to clean them.
In the book there is also a little history about silver valuable chinese coins. I recommend it to you all
Here an example

The Chinese province name is, in fact, Hunan, not Hupeh.
But well spotted.

Quote: "yvon"It is an intresting book indeed, but photo's would have served the same purpose, or even better.
For a real coin-lover all this kind of fakes, replica's or whatever they are called is a real NO-NO...
They are, imo, in they same category as inflatable women.

That is your personal opinion, someone could prefer inflatable women, who knows?
Thank you all for your suggestions, i will try a mixture of bicarbonate and hydrogen peroxide before to buy some product.
Here you have the complete minibook for those interested. Don't expect something professional, it is a turistic stuff, i guess.

Cobrapel: Start with something less harsh than acid and base. Try olive oil or rubbing alcohol. Even water to start with would be better. I soak them over night and use a cotton swab to wipe of the detritus. If you use an acid only soak for a couple of hours at most.
Good luck.

Thanks. I just love these history. Very nice collection. If I have the money, I would buy real ones and make a albulm almost the same.

The real 1900's Chinese dollars and Candereens are extremely hard to find and far too expensive (the most of them ended in the melt pot).
I have 9 of those fakes, some magnetic, some dont, but they're all definately beautiful enough to collect.

Always ready to swap within the Netherlands!

Yup agree. From 1880 to 1950, the South East asia went through alof of war and changes. Japan dominated most of them. China on the other hand was messy. China could have been strong if they unite to repale japan and Russia. But they went divided into clicks (not sure if this is the spelling) and that's why we have this Taiwan and China dispute. I think the last 200 years Asia went through alot of changes and conquest.

Most of the world went through a lot of changes and conquest in the last 200 years.

But anyway, even though in this case the coins are being sold as replicas, the fact that they aren't marked as such (as in on the coins themselves) means that an unscrupulous individual could do so to unknowing customers. They're not even good replicas either, many of them are fantasies, or mashups of two different coins, or have incorrect lettering (like the province error I mentioned above)! That's the reason for our "hate" of "coins" like these.

Edit: On a more general note though, these coins are fairly hard to find but not that expensive; for a genuine, common 7 Mace 2 Candareens type (e.g. Pei Yang or Hupeh) expect to pay around 250 euro for one in VF. I got mine in low F for 120, but that's probably a lowball.
