Hi. I got such a coin, but its authenticity is in doubt. I ask you to express your point of view. The weight of the coin 28.33 - 28.39g.. X-ray fluorescence analysis of surface shows the following composition: Ag 74.15%, Cu 20.01%, Zh 2.67%, Fe 0.183%, Pb 0,147%, 2.84% - other additives.

Sounds like it has too much silver - a genuine 1927 crown is only 50% silver!

But the details look similar to mine, purchased from a reputable dealer long before the Chinese forgery invasion:

I've seen Chinese fakes of these at Boot Fairs, but they always look wrong.

Yeah 74% silver doesn't seem right - The Royal Mint wouldn't have been so drastically off.

Some questions

1. How did you get this coin and who from
2. How much did you pay for it
3. I notice you are in Belarus, not a country that is typically known for its hotspot in buying scarce British coins.
4. Is there a certificate of authentication - or was one offered.
5. Is it magnetic?

If the answers are 1. From China, Russia, Eastern Europe or within the last 10 years - get real suspicious
2. Under $100 USD - Suspicious
3. Could be barking up the wrong tree - sorry but lets face it Belarusians are not usual members here.
4. This is a scarce coin worth several hundred dollars if real and usually any reputable dealer will give you some provenance if its real.
5. If it is - its fake.



Overall - to me the colour is wrong for this type, like NumisRobs they should be slightly yellowy silverish - yours has an iron like polished feel. But the weight is right.

The quarternary alloy was Silver 50%, Copper 40% and Zinc and Nickel 5% each - some minor variation is allowed as often the zinc, nickel and copper were melted together and the silver added later - so it would not 'pickle' the silver and keep it light.

The detail looks wrong - all this evidence to me suggests you have a high quality possibly Chinese lead or steel fake - that has been deliberately aged.

If it's round, shiny and silvery I will love it.

Hi. Thank you for your responses.

1.The coin is received from Australia, bought on eBay.
2.A little over $ 100.
3.No certificate, no provenance.
4.Not magnetic.

I don't think color is an indicator of authenticity. At dealers such coins are found both with toned and without patina, white/light. It seems to me that the coin is cleaned. The surface of the coin was checked by the chemical method (silver nitrate) and X-ray fluorescence analyzer. In terms of thermal conductivity, the coin is similar to silver. Diameter of this coin is about - 38.98/38.99 mm, thickness - is about 3 mm (on an old non-digital caliper).

@Princetane

Although you have written a lot of truths, your opinion was absolutely prejudiced against non-Westerners. I'm also Eastern European by Western perception, but no one has ever complained to me. I sold (and bought) about $ 500,000 in coins. I have never had a complaint and I know about 100-120 Eastern European and Russian as well as Polish collectors and traders, but only 1-2 people who would be breaking the law. This doesn't seem any worse than Western statistics. I don't know what the situation is with the Chinese counterfeiting industry, I don't care, but people who make up a significant part of the population in the Northern Hemisphere are rarely given such a weighty opinion.

Sorry, I just inferenced the EE thing as sometimes I have had begging emails for stamps and coins from Russia, Ukraine and Belarus.

Plus I am assumed that Chinese fakes circulate easily in the era.

I did mention I may be stereotyping in my original post.

I am also not in the Northern Hemisphere or American or European.
