Původ měděného juanu
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.
Ve 23. roce Guangxu (1897) se Chen Qizhang, dozorce provincie Jiangxi, zeptal: „Napodobit velké a malé měděné dolary, aby vydělali za nedostatek peněz.“ achměděný dolar váží 2 mince, obsahuje 95 % mědi, 4 % bílého olova a 1 % cínu. Čtyři čínské znaky „GuangxuYuanbao“ a dva znaky „Baoguang“ jsou odlity na přední straně se slovy "Jeden kruh za každých sto kusů" kolem. Střed zadní části je vyryt plochým drakem a kolem něj jsou slova "Guangdong Yixian" v angličtině. Toto je původní měděný dolar. bylo změněno na „deset slov za každý kus peněz“; anglické slovo „jeden cent“ na zadní straně bylo také změněno na „deset slov“. Nová měď je nádherná a nádherná. Výsledkem je, že různé provincie se řídily. a slova a vzory se také změnily. V současné době byl "měděný yuan otevřen pro lití v deseti provinciích, s mnoha 20 úřady". angxu, 1 709 384 ve 32. roce Guangxu, 2 851 200 ve 33. roce Guangxu a 1 428 000 ve 34. roce Guangxu.
V roce 1905 se vláda Qingu rozhodla vytvořit "Velkou měděnou minci" a tím naplnit měděný dolar a vyřešit zneužití. Existují čtyři typy: dvacet čtyři mincí, deset dvou mincí, pětinásobek jedné mince, advanásobek, kdy se dají použít dvě ryzosti, jemnost 5 čtyřcentů. trendu přehazování se hodnota měděného dolaru každým dnem snižuje.
OnApril16,1910(Xuantong2ndyear),theQinggovernmentwasdeterminedtofundamentallysolvetheproblemofcopperyuan,andpromulgatedtherulesofthecurrencysystem.Whiledeterminingthesilverstandard,italsostipulatedthatthecoppercurrencywasdividedintocents.Therearefourtypes:twopoints,onepoint,fivepoints,andonepoint.Theplanhasnotbeenimplementedthistime,andithasdiedtogetherwiththeQingDynasty.DuringtheperiodoftheRepublicofChina,theseparatistforcesinvariousregionsfoughtagainsteachother,andthenoneafteranothersetupfactoriestomanufacturecopperyuantoraisemilitaryexpenditures.ThemoneylawintheperiodoftheBeiyanggovernmentwasevenworse.Notonlydidtheprovincescontinuetobuildnewfactories,thequalityofcopperproducedwasinferior,andthefacevaluewasincreasedinordertomakehugeprofits.AftertheNorthernExpedition,copperdollarsweregraduallyreplacedbynickelcoinsandgraduallywithdrawnfromcirculation.

Historie mědi yu není dlouhá. Ve dvacátém třetím roce Guangxu (1897) se Chen Qizhang, dozorce provincie Jiangxi, zeptal: „Napodobit velkou a malou měď, kterou si můžete vydělat za nedostatek peněz.“ napodobit hongkongskou měnu a vyrobit měď yuan. Tato měď váží každý 2 yua její jemnost obsahuje 95 mědi, 4 olovo a 1 cín. Na přední straně jsou čínské znaky „GuangxuYuanbao“ a „Guangbao“ s plným počtem znaků Jeden kruh za každých sto" kolem něj. Střed zadní části je vyryt vzorem draka a kolem něj je anglický "Guangdong Yixian". Vzorek tohoto druhu mědi je na světě extrémně vzácný a současná cena je vysoká 25 000 za verzi CASH v měně je 25 000 za kus. Anglického obchodníka na zadní straně a cena je 10 juanů. Běžná měděná měna „Guangbao“ má hodnotu pouze 0,5–1 juan za minci.

Ve 31. roce Guangxu (1905) odlila vláda Qing „Velkou měděnou minci Qing“. Existují 4 druhy mincí tohoto druhu: 1. Když se prodá 24 mincí (tržní cena mince s perličkovým kroužkem na zadní straně je 60 jüanů/kus, o 1 centu je hvězda05 za „kusem“ jüan./kus, obyčejné mají hodnotu pouze 0,5–1 jüan/kus). 2. Když těžké dvě mince (hvězdný bod ve středu je asi 15 juanů/kus, obyčejné mají hodnotu pouze 1-7 juanů/kus). 3.Když je pět mincí a jedna mince (přibližně 50 juanů/kus). 4.Když je dvojitá čtveřice (přibližně více než 60 juanů/kus). mount v té době a byl jednou široce cirkulován a používán mezi lidmi. Na cointradingovém trhu se také běžně prodává „GreatQing CopperCoins“ v dávkách.

Identifikace padělaných produktů
Identifikace falešné rzi
Existuje sedm způsobů, jak získat patinu jednoduchými podmínkami:
Nejprve použijte lak a namíchání barvy: Po smíchání aplikujte na padělané mince a po roce zaschnou a ztvrdnou, téměř jako opravdová rez;
Secondly,userosinorgluetomixwithpaintandpaintonthecounterfeitcoins.Afterhardening,itlooksthesameasrealrust,butthefastnessandcolorareslightlyworse;
Thirdly,usetherealrustofordinarycoppercoinstosticktothecounterfeitcoppercoins.Therustisrealandthecoinsarefake;

Sixth,ifthecounterfeitmoneyisimmersedinasulfuricacidsolution,itwillrustinashortperiodoftime;
>Za sedmé, použijte jemné měděné šroty, smíchejte je s kyselinou dusičnou a očekávaným způsobem a aplikujte na padělané mince do pěstitelského prostředí s relativně pevnou patinou.
Metoda pro identifikaci těchto falešných důvěry:
Za prvé, rtuťová koroze nemůže být získána chemickým ponořením nebo zasypáním půdy; jako jsou: barva, lak, lepidlo atd. Aplikujte po dlouhodobém promíchání. Falešná koroze odpadne.

Pseudobarevná identifikace
K identifikaci falešných peněz je k dispozici také identifikace barev. Některé staré mince jsou bez rzi a budou se používat po dlouhou dobu. Na povrchu se vytvoří tvrdá černá-hnědá nebo bronzová barva, která se nazývá „předávaná z generace na generaci“.
