5角硬币里含黄金？真的还是假的？多亏银行朋友提醒，看完涨知识

Core Viewpoint - The belief that the golden-colored five-cent coins contain gold is a misconception, as their appearance is due to the materials and manufacturing processes used, not actual gold content [1][5][9]. Group 1: Coin Composition - The two main types of five-cent coins in circulation are the Plum Blossom five-cent coins (1991-2001) made of brass and the Lotus five-cent coins (2002 onwards) made of steel core with copper plating [3][5]. - The Plum Blossom coins from 1991 to 1994 were made from imported brass, giving them a color closer to gold, while the Lotus coins have a shiny gold-like appearance due to their copper coating [3][5]. Group 2: Misconceptions and Origins - The misconception that five-cent coins contain gold has persisted for decades, particularly in small towns and rural areas, primarily due to visual similarities to gold [5][7]. - Factors contributing to this misunderstanding include misleading visual cues, the influence of unscrupulous vendors promoting the idea for profit, and limited access to information about currency materials and gold value in earlier times [7][8]. Group 3: Economic Analysis - From an economic perspective, the notion of five-cent coins containing gold is illogical; for instance, with gold priced at approximately 485 yuan per gram, even a minimal gold content would exceed the coin's face value [7][8]. - The manufacturing cost of coins must be lower than their face value to prevent people from melting them for profit, which is a fundamental principle in currency issuance [8]. Group 4: Collectible Value - While five-cent coins do not contain gold, certain years of coins can have significant collectible value based on their rarity and condition; for example, the 1993 Plum Blossom coin can be valued at around 14.8 yuan, while pristine uncirculated versions can reach up to 50 yuan [8]. - The value of these coins is driven by scarcity and collector demand rather than any gold content [8][9]. Group 5: Legal and Health Considerations - It is illegal to alter currency, such as melting coins to create jewelry, which can lead to legal consequences; additionally, coins can harbor bacteria, making direct skin contact unhygienic [8][9].
