The silver line on banknotes is called a security thread. It is a metallic strip embedded within the paper to help deter counterfeiting by adding a visual element that is difficult to replicate.
The Chinese jiazi banknotes are generally considered to be the first paper money in history, entering use around about 960 AD. The first European banknotes were issued in Sweden in 1660.

Many modern banknotes include a thin or thick aluminum coated polyester thread embedded into the paper during manufacture. Many examples are surfaced on alternating sides, giving the impression that the thread has been sewn through the paper. Some notes, including modern Bank of England issues, use a wider strip which has holographic images printed along them. This is a complicated security feature that is difficult and expensive to replicate, making forgeries considerably harder.
Modern issue Chinese banknotes are produced to a very high standard with most of the 'normal' security features, including watermarks, fluorescent inks, metallic strips (on all notes other than the ¥1), raised printing, EURion constellations and differentiated serial numbers.
Security strips in banknotes are typically integrated during the printing process. The strips, made from a polymer material, are embedded within the paper or printed directly onto the surface, using specialized machinery that aligns them precisely. This process ensures that the strips are securely attached and aligned with other security features, making them difficult to replicate. The strips often contain information or patterns that can be verified under ultraviolet light or with other detection methods.
Silver is an element that occurs in nature. It was discovered, not invented, by ancient man.
