钱体不是过重就是过轻，这是因为仿制品与真品所用铜质不同氧化程度不同， 现代造假者，用计算机等最新科技手段分析古钱币的成分或用同时代的普通钱币融化后在铸新钱，所仿造古钱币在材质上足可乱真，不易辨真伪。但鉴定者可从真、伪品的其他方面去突破，主要是不同时代的铸造工艺、书法特点等都会反映在古钱币上。Money body not overweight or underweight, this is because the clones with different degree of oxidation of copper used in the real modern counterfeiters, using the latest technology, such as computers, analyzing the composition of ancient COINS or cast in contemporary common coin melts in new money, the counterfeit coin on the material can be spurious, not easy to tell its authenticity. But the appraisers can make a breakthrough from the other aspects of truth and counterfeits, which are mainly reflected in ancient COINS by the casting process and calligraphy characteristics of different time
高仿品工艺常常过细。高仿古钱币铸造工艺，均比被仿物生产时期先进，而仿造者又惟恐做得不精不细不真，在铸造时常使用当代生产技术，故往往过于精细立体感过强。High - quality imitation is often too fine. High antique COINS casting process, than being advanced production period, imitation and imitators lest do not fine not true, in casting often use modern production technology, are often too fine stereo feeling more.
铸造风格与铸造时代不符。这是最要害的一点。众所周知，不同时期铸造的古钱币其风格不同，因此，仿造品无论怎样精心研究被仿对象，着意模仿特点，仍必然打上仿造者的时代烙印，给辨伪者留下蛛丝马迹。The casting style is not consistent with the casting age. This is the most crucial point. As we all know, the casting in different periods of ancient COINS its style is different, therefore, counterfeits regardless of how carefully research is imitated object, aimed to imitate characteristics, still will be the era of imitators on, leaving clues to scrutiny.
字体轮廓线条生硬。这亦是鉴定作伪品的一个重要突破口。因为仿品是“仿”，现在仿品一般用子钱或塑料雕母翻砂，用子钱翻砂出来的钱有其型无其神，任何高手制作塑料雕母时都有一个参详的蓝本，其制作受该蓝本制约，不能随意，只能尽心尽意去“依葫芦画瓢”。The outline of the font is stiff. This is also an important breach to identify counterfeit products. Because replicas is "imitation", replicas generally with the money now or plastic coin foundry, aluminum casting with child money out of money as the type without the god, any player making plastic coin has a blue print of the searching, its production is conditioned by the blueprint, not casually, can only be striven to "gourd ladle".
无自然流通痕迹。传世古钱币真品大都经历百年，钱币表面有自然磨损痕迹仿品，生产出来的时间不长，当然没有流通磨损。有的仿品虽经人工作旧，但其磨损痕迹不自然，有人为痕迹。No trace of natural circulation. Most of the ancient COINS of ancient COINS have gone through a hundred years. The COINS have natural wear and tear on the surface of the coin, and the production time is not long, and of course there is no wear and tear. Some of the imitations are old, but their wear marks are not natural, some people are trace.
The color of the new copper coating is not correct.
边道穿口形制、方面的一些特征与真品不符，看上去极不自然。这是因为要仿得像、仿得真，仿造者大多研究掌握了被仿真品基本特征，好些作伪者均是研究古钱币的内行。The side channel through the mouth shape, the aspect of some characteristics is not consistent with the original, it looks unnatural. This is because of the imitation and imitation, most of the imitators have mastered the basic characteristics of the imitations, and many of the counterfeiters have studied the inner workings of ancient COINS.
字体无力，字体做作舒展不自然，有些走形不规整，线条粗细不匀。因为能写古钱币书法的都是那个时代有名气的书法家，书法体现的是这人的艺术个性。The font is weak, the typeface is affected by the natural appearance, some are irregular, the lines are not uniform. Because the calligraphers who can write ancient COINS and calligraphy are famous calligraphers of the time, calligraphy embodies the artistic personality of this person.
To do old and false rust, we have an important aspect of the imitation of ancient COINS to do the old fake rust, not old is easier to be seen through. Therefore, the clever imitator also summarized some old ways to do it, the so-called daoism, the monster, which also increased the difficulty of the identification of the collection. We judge the old and false rust of the counterfeiters, and we also summarize some ways to recognize the authorities:
