How to start a Authentic Ancient Coins Collection?

If you are a new beginner and would like to start collecting authentic anceint coins, Here is my recommendation:
1) Buy a coin collection book which you can use as a cross reference.
2) Choose a country you like to collect.
3) Be more focus and targetted.
4) If you can't afford to pay more, then start from later century, then after some years of experience you may upgrade to the next level.
5) Do some reading on that country history you collected these coins.
6) Research on the history of the coin's minted.
7) Research on the background of the coin.

Serious collection studies:
8) Research on the design and pattern of coins
9) Research on those ancient inscriptions
10) Research on their custom and culture

Some try in error;
1) Buy some coins from the giftshops and make a comparison between these coins with your coin reference books.
2) Check on Shapes, design and molding.
3) You may email me for further forum discussion.

Is there a 100% sure authentic /genunine stuffs only when you buy from a Antique shops?
My answer: Not necessary. When I first started my first antique collection, I also bought my stuffs from these shops. It was only some years later after my in-depth study I found out that those products I bought in my early years of collection, not all pieces are genuine stuffs.
There are some of these antiques which was produced/ replica during the era of the Song's dynasty when the Song's emperors took interest in these ancient China Antiques collection.
It was then,there was a lot of those replica coins and antiques vessels of the original Shang , Zhou; Qin and Han artifacts were replicated.
Although it was and can be consider as antique but it was not of the original dating antiques on these replica made during the Song's era.

How can you tell between antiques made from the original era and Song's era?
The answer is simple : Still go back to the basic. Check on the Patina Ageing layers.
The Song's replicas of these antiques cannot acheived the Patina Ageing Coating layers.
And also the Song's era replica on these Artifacts were molded with improvement and better cutting on the design and writing. Hence, it tells the differences between the original era and Song's era products.

Many other fake and imitate bronze coins and artifacts




These are the fake and imitation coins and china artifacts in which it is easily found in Chinatown and giftshops .
Take a look at these coins you can easly detect that these are fake coins.
Even on these artifacts, you also can detect that these are fake artifacts.
Test it for yourself:
1) How to do see that these are fake coins and artifacts?






How to identify Genuine Coin?




Here is another set of coins which you can compare to my previous posting between Fake and Genunine coin.
The differences is clearly seen from the coin appearance color tone of the Patina.
The thickness of the Patina of the greenish color give the period dating that it got its greenish surface not overnight but though many decades.
The wording of " Wu-Zhu" also can be compare to see the differences in the way it was written in the mold.
The shape of the coin during the mold design was also not as neat as you seen from the fake molded coin.
Lastly, the use of the magnifying glass of 10X or more will tell you more story of its authenticity.






How to identify Fake Coin?











Here is a study on Fake Coin which produced to look alike genuine coin. Even the color of the "Patina" is fake color.


The answer can be easily trace through a 10 times or more magnifying glass/ scope test.




Where did it goes wrong?


1st flaw: The design of the coin ( Wu-Zhu) : The character writing was too vivid and neatly written without flaw and irregularities. It is not possible to acheived such neat standard in the period of the Han dynasty.


2nd flaw: The color of the Patina is not natural as compare to the genuine patina growth. The fake patina color is "dim and dead" color as compare to the genuine patina color which is sharp, clear and lively color tones.




3rd flaw : The coin molding is also too neat which is not possible in the Han period.




Does your Antique coin have PATINA Coating?

PATINA is form like a tree bark. The tree bark is not formed overnight. it also take decades.
From the inner layer called the : Cambuim cell layer to Inner Layer and finally to External layer which enable us to tell the ageing process of the tree and the age of the tree.
Therefore, if you want to know whether the antiques ; coins; artifacts are real genuine or fake, the first step is to identified the existence of Patina's presence in the product.


The British bronze coin dated in 1866 is consider relatively young coin. That is why there isn't any trace of Patina found on the coin's surface.

Below is the coin from one of the Qing Dynasty which was dated around 1644AD to late 1800. It is also consider pretty young coin. That is why there isn't any trace of Patina found on the coin's surface.



These coins are from ancient Israel dated around 25AD to 220AD . Thin layer of Patina can be found on these coins.

Here is another coin from the Zhou Dynasty dated between 11th BC to 770BC. It has a visible layer of Patina on the whole coin. The color tone of the Patina from light to dark greenish indicate the ageing process .


The Patina Color which is light green found on the bronze statute of the liberty was a man-made chemical process patina. These man-made Patina's coloe re-created look-a-like real patina.
However, to prove whether it is real or fake is to take a scatch on the patina and check on its layers. A man-made Patina only have a surface coating. A genuine Patina will have multiple layers Patina coated. It will proves its authenticity.










One of the first basic step to collect ancient coins is to understand some basic metal appearance that changes from time to time.

And the first thing to take note in order to determine whether the coin is genuine or fake is by tracing for the existence of : PATINA which are found on the surface of the coin-metal.


Patina (ˈpa tə nə) is a film on the surface of bronze or similar metals, produced by oxidation over a long period, sheen on wooden furniture produced by age, wear and polishing, or any such acquired change of a surface through age and exposure. On metal, patina is a coating of various chemical compounds such as oxides or carbonates formed on the surface during exposure to the elements (weathering). Patina also refers to accumulated changes in surface texture and colour that result from normal use of an object such as a coin or a piece of furniture over time.


Appearance of Patina: Different tones of greenish color. From light to dark green to deep ocean blue-green.

The green patina that forms naturally on copper and bronze is known as verdigris and consists of copper carbonate.
One example of a patina is a green surface texture created by slow chemical alteration of copper, producing a basic carbonate. It can form on pure copper objects as well as alloys which contain copper, such as bronze or brass.



PATINA give the authenticity value of these ancient coins and artifacts:


Apart from the aesthetic appearance and practical protection of patination, antique experts confirm that an object's value increases when its patination is intact because it is an important effect of the ageing process and this evidential history is reflected in the value of the piece.
In terms of antiques then,Patina is everything that happens to an object over the course of time. The nick in the leg of a table, a scratch on a table top, the loss of moisture in the paint, the crackling of a finish or a glaze in ceramics, the gentle wear patterns on the edge of a plate. All these things add up to create a softer look, subtle color changes, a character.


Can Patina be found in modern coin?

No, it take decade to create this natural substance which grow on the surface of bronze material.

Therefore, it is easy to differentiate between fake and genuine coins and artifacts by trace of Patina.


However, there be possible trace of Patina found on modern coin. Nevertheless, the Patina thickness and its color tones cannot be compare to those Patina which already grown on the ancient coins or artifacts can tell the ageing process of the product. A genuine Patina ageing process can be tell by its layers process found on Patina layers. A man-made patina will not have such ageing layers.
