美國政府早前宣布,鑒於聯邦預算的削減,美國二十一任總統 Chester A. Arthur 的流通幣將暫停發行,而原本於上星期發行的溢價總統幣何時發行直到現在也沒定案("As will shock you all," Vice President Biden drolly noted in announcing the suspension of the $1 Presidential Coin program, "calls for Chester A. Arthur coins are not big." )幾個星期之前,Senators John McCain (R-AZ) and Tom Harkin (D-IA) 發表聲明,支持硬幣的使用。一個振奮人心的計劃也被提出,未來四年將phase out $1 紙幣的生產以推廣硬幣流通。但其中一個隱憂就是,美國$1 coin 太容易被造假,如果大量使用$1 coin, may leave a half-billion-dollar hole in our pocket,因為counterfeiting。
據歐洲最新Euro coin counterfeiting in 2011報告統計,Their European Technical and Science Centre intercepted 157,000 bogus euro coins in 2011。The report's year-to-year figures reveal that faked 50-cent and 1-euro coins, worth about 66 cents and $1.32 respectively, have been steadily increasing in number for the last four years。
由於大量假幣的出現,現在各國都在積極尋求鑄造技術上的更新,以便更好地阻止和震懾假幣的泛濫。
2012年,加拿大將發行新款$1 和 $2 流通幣,除了造價考量,一個主要原因也是為了防假,這次新發型的一元和兩元幣采用了laser-marks and electromagnetic signatures meant to deter counterfeiters。Planned anti-counterfeiting technology to make its debut on the coins includes the use of a lasermark maple leaf on the reverse of each $1 coin and two “virtual image” maple leafs “between two lines at the top of the coin and the words CANADA and 2 DOLLARS interspersed with two lasermark maple leaves each within a circle at the bottom of the coin。” In addition, edge lettering of CANADA and 2 DOLLARS,with a maple leaf flanking each side of CANADA,will be used on the $2 coin。
Canada’s $1 and $2 coins will soon sport technological upgrades to deter counterfeiting, and new compositions to save the Canadian government millions annually. Examples of current composition 2011 coins appear here。
鑒於新技術和版本的初次使用,按照以往經驗,mint 最初鑄造出來的硬幣比較容易發現錯幣(短時間內被造假的可能性不大),尤其是edge letter,美國07年發行的第一枚總統幣初期就發現有miss edge letter 幣現象。同學們可以在收到新的Loonie 和 Toonie 時多多留意,仔細觀察,一旦發現與官方描述不符的情況一定好好保留錢幣,說不定寶貝就在你手中
