古钱币收藏是一些藏家的心头好,大发国际\大发国际开户\大发国际注册:但是随着古钱币的升值,造假的现象也逐渐多了起来,让人眼花缭乱,那么还不是很内行的藏家该如何分辨呢?
The collection of ancient coins is a good idea of some collectors. But with the appreciation of ancient coins, the phenomenon of counterfeiting is getting more and more dizzying. So how do we distinguish between Tibetan collectors?

现代古钱作伪中采用最多的是翻砂法。翻砂法以真钱原品制作模型,浇铸的铜水多为古代铜钱或铜镜熔化而成,因此翻铸铜质仍接近古时的青铜或红铜。由于热胀冷缩的缘故,以真钱翻钱要略小于真钱。此种伪钱上市极多,有的几可乱真,只在锈色、包浆上会露有马脚,鉴定时一定要注意。
The modern coins or is used in most of the foundry method. The foundry method with real money making the original model, cast copper water for ancient coins or bronze mirrors and therefore cast melting, copper is still close to the ancient bronze or copper. As a result of risk factors, with real money over money is slightly less than the real money. The pseudo money listed very much, some real thing, only in the rust, patina will exposed himself away, attention must be paid to the identification.
古代铸钱工艺都比较讲究,故铜钱质地细密,光洁度高,表面有自然磨损的痕迹。伪造者的翻铸工艺一般都很差,因此铜质疏松,表面多砂眼、气孔,即使经过了打磨,也不如自然磨损那样温润、光亮;古代铸钱时只将砂箱翻身,不需要将母钱一一拿出,因此砂模受力均匀,钱币的厚薄也大体相同。伪造时,真钱被用做模,取钱时砂范受力不均,往往会造成轻度变形,所铸伪钱在厚度上也有出入。
 
The ancient money casting technology is more exquisite, so the copper money is fine and fine, and the surface has the trace of natural wear. The forger cast process generally is very poor, so the copper surface is loose, sand holes, porosity, even after grinding, as well as the natural wear warm and bright; the ancient cast money will only sand box turn over, do not need to be the mother of money out, so the sand mold uniform stress, the thickness of the coin roughly the same. When forgery, the real money is used as a mold. When the money is taken out of the sand, it often causes slight deformation, and the counterfeit money is also discrepant in the thickness.
此外,出炉后不久就被埋入土中的古钱,若干年后出土时仍文字清晰,能看清原始锉痕;如果古钱流通过久,轮廓就失去了棱角,锉痕当然也就消失了。如发现文字平夷而钱体上却有新锉痕的钱币,藏家就应仔细察看了。
In addition, released shortly after being buried in the ancient coins, some years later still unearthed text clear, can see the original file mark; if the coin circulation is too long, will lose the contour edges, file marks will disappear naturally. Such as the discovery of text and money planation body there is a new file marks coins, collectors should be carefully examined.
