1999 Banco Nacional Ultramarino (BNU) Macau 20 Patacas: In-depth Analysis & Collector's Guide
📝 Overview of the Macau 20 Patacas (BNU) Specifications
The Macau 20 Patacas (BNU) was one of the banknotes specially issued in 1999 to commemorate the Handover of Macau, and it has attracted significant attention from collectors. In that year, this version of the banknote contained an error where the character"Bei"(bèi) was printed as an"open-mouth"character. This directly led to a surge in its price. It is important to note that the process of issuing banknotes is extremely complex and rigorous, making it very rare for misprinted banknotes to occur. Due to its scarcity, it naturally became highly sought after. In fact, after the misprint was discovered, the official authorities continuously recalled the Macau 20 Patacas (BNU). Currently, very few 1999 versions of the Macau 20 Patacas (BNU) circulate on the market.

🔍 In-depth Exploration: Why is the "Open-Mouth" BNU 20 Patacas More Valuable?
Among the 20 Pataca banknotes issued in Macau in 1999, the Banco Nacional Ultramarino (BNU) version gained notoriety for its unique"misprint"controversy. The **"open-mouth Bei"** (kāikǒu bèi) that collectors refer to describes the character"Bei"(bèi) at the bottom of the"Yuan "(yuán) character on the banknote, which differs from regular fonts and appears to be unclosed.
- Scarcity: As this version was not widely noticed at the beginning of its issuance, official authorities made adjustments in subsequent printings. This led to a significant reduction in the number of "original misprints" circulating on the market.
- Authentication Point:A truly collectible"open-mouth Bei"requires observing the ink distribution and continuity of lines in the character. Professional collectors usually look forhigh-grade PMG or PCGS slabbed notes to ensure their authenticity and condition.
- Historical Significance: As one of the first banknotes issued after the Handover, the BNU version represents a turning point in the history of Western banks issuing currency in Macau. Its cultural research value is no less significant than its market circulation value.
