A friend just bought this, any opinions on authenticity?

I'm the guy who bought the coin. I intend to weigh it as soon as I receive it. If the weight matches Krause, I'll probably have it sent out to be professionally graded.

Can anyone enlighten me on this coin's authenticity?

I am not familiar with the series, but the toning looks suspicious and consistent with some low-content silver "tourist" dollars I have seen come out of China.

I don't want to disappoint you, so I'll wait for someone with more experience in the series to post.

Sorry but I don't agree that it's genuine. Striking of such Soviet silver coins are extremely crude and I never seen any that is in such fine shape. Krause prices on such Soviet-Chinese coins are off and genuine ones that I have seen are extremely pricy.

Weight alone is a very bad test as silver Chinese coins were melted down to make such coins. Specific gravity test will not work as well as it is easy to find cheap worn or damaged Chinese silver coins to fix the metal content. Remember, those coins were minted in such crudeness that you most probably at best have a restrike but I doubt it.

Actually, these coins were made with great detailing. If you look at page 433 of Krause, you'll notice they're not supposed to be crude. Also, they're all quite rare. Nobody would melt down a coin worth hundreds to dollars to make a fake one worth hundreds of dollars.

I just received it today (the seller lives 30 minutes from my house), and will be buying an electronic scale to accurately weigh it.

If you look here, you'll see real and fake coins like mine: http://www.moneta-coins.com/photopo...way=&cat=all

What I want to know is if there are distinct ways of authenticating this, other than weight.

CalloftheHauntedMaster, the striking of these Soviet dollars are not too excellent. In fact, if you noticed with your coin there, the Chinese characters and other legends all look completely WRONG unless you got a different variety there. When I mean they look completely wrong, please kindly look at the thickness of the characters.

Here might be a better one to compare with:

http://coins.heritageauctions.com/c...12711&src=pr

Note the price tag - a genuine one is more likely to cost near 4 figures.

Furthermore, that particular coin does not look like a typical Chinese silver coin minted back then. And no, you don't understand the level of counterfeiting in China. You can get CHEAP chinese silver junk coins, melt it down and then make new coins out of them. Such damaged silver coins in China don't even cost bullion values at times.

I'll be weighing this coin tomorrow using the analytical balance in my Chem Lab.

If it checks out, I'll go to step 2, which is sending it to a professional company to have authenticated and/or graded.

The one thing we can all agree on is that it is definitely silver. The markings vary as even Krause's pictures aren't all inclusive.

We'll know more once the numbers are up.

As for those darn Chinese counterfeiters, it's just a shame Mao wasn't into numismatics.

Sorry to jump into this discussion late - but I have been very busy with three collections I have purchased recently.

In this particular case I will give odds against the coin being real. The dies are simply wrong. This coin is most likely a very recent strike in silver made with dies that were photo etched into steel plates. I would guess that the edge shows the wrong detail because it was most likely added AFTER the coin was made by a process not used on originals. Most copies I have examined in person (and the one I own) have a reeded edge applied with a ring die. If there are reeds look for split tops or incomplete reeds.

The way to tell a photo etched die is the texture of the surfaces produced by the recessed areas in the die. If the strike fully fills the die, the metal extrudes and copies the surfaces inside the letters cut into the die. When the deepest part of this protected surface shows - you not only have a mint state coin - you have a method you can use to determine if the die was engraved or punched. In either a punched die or an engraved die this surface is key. Original coins were made with letter punches which were driven into the steel die surface. The flat surface of these punches leave groves in that surface very similar to the rifling in the barrel of a gun. On a high grade coin you can identify the individual punch used to make the die by these "lines". When a die is made by electro-erosion or photo engraving - these minute lines are NOT copied. The whole coin would be covered with a similar texture except that the outer portions of the die can be smoothed. The forgers can and do lap (file) the die surfaces (which produces the fields of the coin) but the recessed portions of the die can NOT be polished. The resulting texture is "rough". Looks kind of like a spark erosion die but a tad cruder on the photo-engraved dies I have observed.

This photo-engraving technique is the technique used to create most of the 1882 Zs 8R forgeries. It is quick and produces a poor copy.

Regarding melting old Chinese silver for these coins - you don't need to melt a rare coin to get the material. You can melt a few Fat Man dollars or their restrikes and secure the same raw material the Communists used for the originals. Old junk Fat man dollars trade at bullion. But the general idea contained in the comment that "salvaged silver" defeats many of the more common tests like weight, ring and SG is right on.

Also, I believe I can see a marginal ring on a portion of the rim. This often is passed off as a collar seam but this one really looks suspect to me. Look specifically at the rim between the numbers 1 and 3 under the hammer and cycle. The "collar seam" line is NOT concentric. That undulation (if it is present on the coin) is 100% impossible on a real coin unless there are deep rim nicks but such a weaving or undulation is commonly seen on fakes.

I also agree with the comment that the Chinese characters look bogus. They are not sharp as if created by a character punch but seem to merge into one another. This is a poor rendition of the figures. Chinese characters (they are not letters) are compositions that contain individual strokes which have significance based on position, thickness and even direction. The characters here are quite frankly a meaningless hodge podge.

In my opinion, the cost of certification exceeds the value of this coin by a factor of 2 to 3. But to be certain be my guest.

Please let us know the outcome. I have been known to be wrong at times and I can only hope that is the case here because of the cost involved, but I really doubt it.

I went to my friend who runs a coin store and is a professional. He weighed it on two different electronic scales and got 24.7 grams. My dad still believes the loss in weight could be due to the wear. I think it's fake. Opinions?

CalloftheHauntedMaster Simply stated the weight is too low.

An original coin in mint state should weigh about 26.3 grams. Your coin weighs about 94% of that amount. Wear never accounts for quite that much loss of metal. Studies done by the US mint prior to 1964 proved that less than a 5% loss of weight resulted in a coin that was almost worn totally flat. The relief on a real silver coin is not actually as high as you might think. There are some other threads that covered that topic. In the condition that your coin appears to be - it should weigh about 25.7 to 25.8 grams.
