South African coins do often come in a "funny colour", largely because of the peculiar alloys they used. These are made of .800 fine silver.

Though the mintage is only 300,000 one in that condition would only be worth bullion value.

This one looks "fair dinkum" to me (That's OzSpeak for "I think it looks real").

Thanks!

Since the mintage is only 300,000, why is it so inexpensive?

Supply and demand. Nobody wants one.

Very few people apparently collect this coin series.

The coin has the look of a forgery to me but I am not 100% sure from this scan. The coin appears to use clashed dies - you should look at the clash and the other surfaces under 30X or so to see if you have a surfaced steel die or a cast surface. The pattern is correct so if it is fake it is a transfer die or mold. There is a partial collar seam visible on this one that looks wrong but that said I own an original that has such a seam. It is indicative of a worn press where the collar die is worn alowing some metal to displace the collar slightly during the strike. It is also seen on many forgeries especially the ones that need to have a slightly increased diameter due to shrinkage of the transfer matrix (applies to cast transfer dies and molds).

To be 100% sure what you have you need to do two things. First weigh the coin. It should weigh about 28.25 grams in this condition. Anything under 28 grams is suspect, but most of the Chinese fakes run in the 21 - 22 gram range. The typical forgery is a cheap white metal injection molded item. They are sold for $1 by street vendors in Honk Kong. Most buyers think they are getting cheap silver. All they actually are getting is a lesson in greed.

Second check the edge. I believe the originals are made with standard reeds |||||| - look at the reeds themselves and see if there is a split in the top of the reed. This is an indication that the reeds were apploed with a ring die. Most cheap Chinese copies are pressed through a ring die which cuts reeds onto the edge of the coin. This produces a reed with an unnatural look.

I am not yet aware of anyone producing a full weight copy of this coin. To do so in white metal would mean a coin that is far too thick. A silver plate seems out of the question because of the color. Electroplates are pure silver (the nature of the process dictates this). An electroplate will look too dark - pure silver is a darker metal than an 80 or 90 percent alloy that we are used to.

Of course a full weight struck silver forgery is a bit out of the question since there is essentially no margin for profit.

I own both originals and forgeries of this particular coin. I also own copies of each die for this coin mated with other dies from different countries - those are part of a whole series of mules that hit the market a couple years ago from China.

Let us know the results.

Swamperbob, thank you!

Here are 2 pictures of its edge, which just composes a whole round.

Alf_coin - those pictures are perfect to illustrate what a "split top" reed looks like. That coin was definitely reeded by forcing it through a ring die. The coin is counterfeit.

The top scan also shows how the sharp edge was ground down to remove most of the "split tails" on the reeds. Notice how the sharp corner has been ground off UNEVENLY. This is typical since it is a manual operation. Most coins show file or grinder marks on that rounded transition.

Usually the reeds are formed a little better than this and the split occurs only at the ends - but this coin must have been a fraction of a mm too small or slightly out of round. There seem to be some fully formed reeds also - these are more typical and all you see is a trace of the seam at the top center of the reeds where the metal was forced together to fill the groove.

I hope that didn't sound like it was a statement towards you, I was just making a obversation not anything to do with any specific individual. Like I said, I am sure some US coins there are legit coins, it just seems like most of the ones that comes to the mark place are contemporary counterfits for some reason. If it sounded like an attack on you or a specific area I appologize because that is definately not what it was meant to be

Oh, no, Bryan1315, never mind!

Actually, I hate to say that I'm really ashamed of my fellowmen's tireless interest in counterfeiting.

it is very heard for a untrained eye, if it werent for a member here with the nick swamperbob I would be totally in the dark on fakes myself. I have read many posts of his and I can finally start seeing what he's talking about on certain things, but there are still some things that totally catch me off guard. If I ever have a question I will just upload all 3 sides (obverse,reverse,reeded edge)on here and ask him his opinion on it and as much as I would hate to hear it is a fake if he said it was that would be the end of the story because he is the most knowledgable person on fakes that I have ever seen

Natsud - hello and welcome to the forum. I am going to start by saying one thing - it's NOT easy at first to spot a fake in a picture, so don't get discouraged. However, after some experience looking at fakes it does become rather obvious. I got my first fake coins in 1960 or so and have been in love with the topic since. My advice is to take this in small steps.

Once you have selected a type of coin you want to collect start by learning everything about how that particular coin was produced. Was it struck from hubbed dies or engraved dies? Was it cast? Or struck on cast planchets or rolled planchets? Was the planchet upset? When was the edge applied? Did the coin press use a collar die or dies? What does the edge look like anyway? There are many, MANY other questions. Then look for clues on the coin that point toward or away from those methods. Finally get familiar with how forgers work. Larson's recent book on forgery is a great starting spot to detect Modern Forgery methods.

Here is the ANA library listing.

AA70.L3
Larson, Charles Martin
Numismatic forgery, an illustrated, annotated guide to the
practical principles, methods, and techniques employed in the
private manufacture of rare coins.

N.p., n.pub., 1995. 295p.
COINS--COUNTERFEITS & COUNTERFEITING"

The first thing I usually have when looking at a scan on ebay is a "gut feeling" that something is wrong. Sometimes I have to figure out what it is, but usually there are clear reasons.

Prepare to be fooled - especially at the start. It happens all the time. But I think I am doing well if I get 19 out of 20. I also end up with a lot of "suspect" coins that sit there until I find out more about how a particular coin was made. At times, the suspects will change category depending on what new facts about production might come to light.

Just a couple weeks ago, I was authenticating and attributing an estate collection that included 14 1 Real cobs from the reign of Charles II dated in the 1680s to 1700. (Cobs are not things I really care for). Not one was the correct weight and all had Specific Gravities in the 9 to 9.5 range. Silver coins over 0.900 fine should be about 10.34 and copper is about 8.9. These are all clearly debased and combined with being underweight they averaged about 50% of the standard intrinsic value. None were clipped or filed. So I thought they must be modern fakes - cased closed a "slam dunk". This position was reinforced by the fact that the collection also contained two later 8R counterfeits and a cast copy of a French 40 Franc from the 1830s.

WRONG!

After contacting someone more expert than myself (Dan Sedwick - who co-wrote the Practical Book of Cobs third edition) I had to stand corrected. He informed me that the Peruvian and Bolivian mints in the late 1600s were always making debased lightweight minor coins. He believes that they are real mint made coins - but debased. So they fall into that hotly debated category of fraudulent mint issues. Because they are so common - they are treated and apparently priced as "real".

So, sometimes facts that would make for a perfectly clear decision in the year 1800 might be incorrect in 1700 because the standards of production changed.

If any of what I have said raises questions - please ask. The only dumb question is the one you don't ask.
