"a、90版真币有"100"、"YIBA"、"50"、"WUSHI"。
b. The new version of the real currency has a golden yellow fluorescent hidden mark of the numbers 100, 50, 20, 10, 5, and 1 on the front, and there is fluorescence on the back; the currency without fluorescence does not have this feature.

2: Another end is a water-based money-detecting pen: Just use it to mark a real coin, and if it shows its original color, it's real money; if it turns black, it's fake.

This pen is a professional currency verification pen. It can distinguish the authenticity of banknotes, checks, and securities from most countries in the world. As long as you draw on a banknote, genuine currency will show a light yellow or colorless and can disappear automatically without leaving any trace; false currency will show black or brown and the color will be difficult to disappear and will leave a trace.
