古钱币的市场如此火热,但高收益的同时造假猖獗.

       

1、翻铸法

此种方法以真钱(qian)(qian)原(yuan)品做模子捏造。浇铸(zhu)(zhu)铜(tong)水多(duo)为现代铜(tong)钱(qian)(qian)或铜(tong)镜熔解而成(cheng),是以翻铸(zhu)(zhu)铜(tong)质仍(reng)为青铜(tong)或红(hong)铜(tong)。由于热(re)涨冷(leng)缩(suo)原(yuan)因,以成(cheng)本翻钱(qian)(qian)要小(xiao)于成(cheng)本,即翻铸(zhu)(zhu)小(xiao)一匝(za)。此种伪钱(qian)(qian)上市极多(duo),有的几可(ke)乱真。

2、改刻法

抉择旧铜钱较厚的的磨去原有笔墨(mo)(mo),改(gai)(gai)(gai)刻(ke)(ke)另(ling)一(yi)(yi)种稀见品(pin)来(lai)捏(nie)造(zao)。此种捏(nie)造(zao)品(pin)为数不少(shao)。如(ru)五(wu)(wu)铢改(gai)(gai)(gai)刻(ke)(ke)为太清丰乐,小(xiao)货泉(quan)改(gai)(gai)(gai)刻(ke)(ke)为永光景和(he)等。另(ling)有抉择铜钱文(wen)制模糊的添(tian)刻(ke)(ke)笔墨(mo)(mo)或(huo)星月,如(ru)改(gai)(gai)(gai)刻(ke)(ke)半两为两两或(huo)半半,改(gai)(gai)(gai)刻(ke)(ke)五(wu)(wu)铢为五(wu)(wu)五(wu)(wu)或(huo)铢铢。用(yong)各种方法别树一(yi)(yi)帜。

3、粘合拼接法

此种方(fang)法(fa)多用于连泉、合背、同(tong)文钱(qian)(qian)。取(qu)雷同(tong)品两(liang)至数枚,磨去没钱(qian)(qian)的一部(bu)分,粘(zhan)合拼接,即(ji)成(cheng)连泉、合背或(huo)同(tong)文钱(qian)(qian)。另有磨去二个旧钱(qian)(qian)的背,拼合起来成(cheng)为两(liang)面笔墨。

4、光彩作旧法

出土(tu)古(gu)钱(qian)历经(jing)百(bai)年公开腐化,有的浑(hun)身葱绿(lv)、有的红、绿(lv)、黄(huang)、白,斑班驳(bo)驳(bo),货币界称为“活(huo)埋锈”。传世的古(gu)钱(qian)由于久长玩(wan)赏,油汗入表(biao),钱(qian)体呈(cheng)黄(huang)褐或褐色。作伪(wei)者(zhe)为获(huo)得“活(huo)埋”、“传世古(gu)”的外面后(hou)果(guo),湖(hu)南(nan)电视台《西方寻宝》报名:《一八六八四九二四二九九 》(编(bian)导)便在(zai)伪(wei)钱(qian)光彩上作旧。罕(han)见(jian)的方法(fa)以下:

1、看铜质定真伪

古代(dai)铜(tong)(tong)钱(qian)的材质有青铜(tong)(tong)、白(bai)铜(tong)(tong)、红(hong)铜(tong)(tong)和黄铜(tong)(tong)四种。明(ming)代(dai)嘉靖以前(qian)铸(zhu)钱(qian)材质一(yi)般(ban)都是(shi)青铜(tong)(tong),少量白(bai)铜(tong)(tong),红(hong)铜(tong)(tong)铸(zhu)币辽代(dai)较多。青铜(tong)(tong)容易断裂(lie)(lie),断裂(lie)(lie)面无(wu)铜(tong)(tong)色(se),而(er)将(jiang)断裂(lie)(lie)面在石头上摩擦后(hou)(hou),铜(tong)(tong)色(se)即显。黄铜(tong)(tong)铸(zhu)币和铜(tong)(tong)雕(diao)母钱(qian)始于明(ming)代(dai)嘉靖,如果发现明(ming)代(dai)嘉靖以前(qian)的黄铜(tong)(tong)钱(qian)币或铜(tong)(tong)雕(diao)母钱(qian),可判定是(shi)后(hou)(hou)铸(zhu)无(wu)疑。

2、听声音定(ding)真伪

古铜(tong)钱(qian)年代越(yue)久(jiu),钙化(hua)(hua)越(yue)严重,钙化(hua)(hua)后的铜(tong)钱(qian)失去铜(tong)的原声,用金属(shu)撞(zhuang)击声音(yin)沉闷,声音(yin)越(yue)小,时间越(yue)久(jiu)。凡是发现(xian)声音(yin)尖高的古铜(tong)钱(qian),说明没有钙化(hua)(hua)现(xian)象,可判定为(wei)新彷(pang)品(pin)。

3、闻气味(wei)定真(zhen)伪

古钱币真品由于长期埋入(ru)地下(xia),生有(you)(you)(you)锈(xiu)色,出土时会带(dai)有(you)(you)(you)一股纯正的泥土香味(wei),没有(you)(you)(you)别(bie)地异味(wei)。而假钱带(dai)有(you)(you)(you)伪造的锈(xiu)色,有(you)(you)(you)刺鼻(bi)的胶(jiao)水味(wei)、松香味(wei)、生漆味(wei)等怪味(wei)。

4、观锈(xiu)色定(ding)真伪

古(gu)(gu)铜(tong)(tong)钱(qian)停(ting)止流通后,存放不当(dang)会生(sheng)锈(xiu)。传世古(gu)(gu)铜(tong)(tong)钱(qian)锈(xiu)层(ceng)(ceng)较(jiao)薄(bo),且(qie)锈(xiu)在局部,钱(qian)面大部分呈(cheng)古(gu)(gu)黑色。出(chu)土铜(tong)(tong)钱(qian)坑口不同锈(xiu)色不同。土坑出(chu)土的铜(tong)(tong)钱(qian),锈(xiu)层(ceng)(ceng)一般较(jiao)厚,锈(xiu)在一起的铜(tong)(tong)钱(qian)叩开后,有(you)“泛(fan)金”、“泛(fan)银”、“泛(fan)蓝”现象,“三泛(fan)”现象是无(wu)法仿(fang)制的;
