Kupariuanin alkuperä
Theearliestcoppercoin(machinedcoppercoin)inChinawasborninthethirteenthyearofGuangxubyZhangZhidong,thegovernorofGuangdongandGuangxi.In1887,theGuangdongMintwasestablished.InthefifteenthyearofGuangxu(1889),theproductionofmechanicalcopperyuanbegan.Thiswasthebeginningofthe"mechanicalcoin"inthehistoryofChinesecoinage.AftertheSino-JapaneseWarof1894-1895,theimperialistpowerssetoffafrenzieddivisionof"spheresofinfluence"andseizuresof"rentalland"inChina.Withtheintensificationoftheimperialisteconomicaggression,China'sforeigntradehasrepeatedlyenteredintoexcess,alargeamountofsilveroutflowsandheavywarreparations,theQinggovernment'sfinancialpanichasbecomeincreasinglyserious.Atthesametime,duetoimperialistinvestmentinChinaforpredatorypurposes,objectively,China'scapitalistindustryandcommercehavedevelopedtoacertainextent.Asaresult,thesociety'sdemandformoneyisincreasingdaybyday.Thecopperdollarcameintobeingunderthisspecifichistoricalcondition.
Guangxun 23. vuonna (1897), ChenQizhang,Jiangxin maakunnan valvoja, kysyi "Jäljittele suuria ja pieniä kuparidollareita rahanpuutteeseen." Jokainen kuparidollari painaa 2 kolikkoa, jotka sisältävät 95 % kuparia, 4 % valkosipulia ja 1 % tinaa.Neljä kiinalaista merkkiä "GuangxuYuanbao" ja naiset "Baoguang" on valettu eteen, ja sen ympärille sanat "Yksi ympyrä jokaistasadasta kappaleesta".Takaosan keskikohta on kaiverrettu litteällä lohikäärmekoristeella ja sanat "GuangdongYixian" englanninkielisessä osassa. vaihtui "kymmeneksi sanaksi jokaiselle rahalle";englanninkielinen sana "onecents" takana vaihtui myös "kymmeneksi sanaksi".Uusi kupari on hieno ja upea. Tämän seurauksena useat provinssit ovat noudattaneet mallia. jasanatjakuvioita on myös muutettu.Tällä hetkellä"kupariuaani on avattu valuprovinsseja varten,kuten 20 toimistolla".LiangQichaon tietueiden mukaan pronssivalujen määrä jokavuonna oli1,741,167,30.9. Guangxu, 1 709 384 Guangxun 32. vuonna, 2 851 200 Guangxun 33. vuonna ja 1 428 000 Guangxun 34. vuonna.
Vuonna 1905 Qinghallitukset päättivät unohtaa"GreatQingCopperCoin"-sävyälyhytkupardollarinjaratkaisivat väärinkäytön.On neljä tyyppiä:kaksikymmentäneljäkolikkoa,kymmen-kaksikolikkoa,viisinkertainen yksikolikko,jakaksiviisävenäinenneljäkymmentätasoinen. Ei-hyväksyttävän sateensuunnan vuoksi kuparidollarin arvo heikkenee päivä päivältä.
OnApril16,1910(Xuantong2ndyear),theQinggovernmentwasdeterminedtofundamentallysolvetheproblemofcopperyuan,andpromulgatedtherulesofthecurrencysystem.Whiledeterminingthesilverstandard,italsostipulatedthatthecoppercurrencywasdividedintocents.Therearefourtypes:twopoints,onepoint,fivepoints,andonepoint.Theplanhasnotbeenimplementedthistime,andithasdiedtogetherwiththeQingDynasty.DuringtheperiodoftheRepublicofChina,theseparatistforcesinvariousregionsfoughtagainsteachother,andthenoneafteranothersetupfactoriestomanufacturecopperyuantoraisemilitaryexpenditures.ThemoneylawintheperiodoftheBeiyanggovernmentwasevenworse.Notonlydidtheprovincescontinuetobuildnewfactories,thequalityofcopperproducedwasinferior,andthefacevaluewasincreasedinordertomakehugeprofits.AftertheNorthernExpedition,copperdollarsweregraduallyreplacedbynickelcoinsandgraduallywithdrawnfromcirculation.

Kupariuanin historia ei ole pitkä.Guangxun kahdeskymmeneskolmannessa vuodessa(1897),ChenQizhang,Jiangxin maakunnan valvoja, kysyi"Jiangxin maakunnan esimiehenä "Jäljittele isoa ja pientä kuparialuotetta rahanpuutteen vuoksi." toimita Hongkongin valuuttaa kuparijuanin valmistamiseksi.Tämä kuparijuaani painaa 2 yuania,ja sen hienoussisältää 95 kuparia, 4 lyijyä ja 1 tinaa.

Laskettu aikaan,ja olemassa on paljon olemassa olevia. Kolikkomarkkinat myyvät vain 0,5-1 yuania per kolikko.Takana olevan englanninkielisen kirjeen väärä versio on "TENCASH", jonka arvo on 10 yuania per kolikko.

Väärennettyjen tuotteiden tunnistaminen
Väärennön tunnistaminen
On olemassa seitsemän tapaa väärentää patina yksinkertaisilla termeillä:
Käytä ensin lakkaa ja maalisekoitusta: Sekoituksen jälkeen, levitä väärennetyille kolikoille, ja puolen vuoden kuluttua ne kuivuvat ja kovia, melkein kuin aitoa ruostetta;
Secondly,userosinorgluetomixwithpaintandpaintonthecounterfeitcoins.Afterhardening,itlooksthesameasrealrust,butthefastnessandcolorareslightlyworse;
Thirdly,usetherealrustofordinarycoppercoinstosticktothecounterfeitcoppercoins.Therustisrealandthecoinsarefake;

Sixth,ifthecounterfeitmoneyisimmersedinasulfuricacidsolution,itwillrustinashortperiodoftime;
>Seitsemänneksi, käytä hienojakoisia kuparirouheita, sekoita typpihappoon ja odotettuihin ja käytä sitä väärennösrahaan, jotta se kasvaa suhteellisen lujaksi patinaksi.
Menetelmä näiden väärien perusteiden tunnistamiseksi:
Ensinnäkin ruostetta ja elohopeaa ei voida saada kemiallisella upotuksella tai öljyhautauksella; kuten: maali, lakka, liima jne. Levitä sekoittamisen jälkeen. Väärennösputoaa.

Pseudovärintunnistus
Värintunnistus on myös vääränlaisen rahan tunnistamiseksi. Joitakin muinaisia kolikoita käytetään ruosteeton ja sitä käytetään pitkään. Pintaan muodostuu kovamustaruskea tai pronssiväri, jota kutsutaan "siirretty sukupolvelta toiselle".
