إلى متى ستبقى النقود الورقية في الخزنة؟

Could you elaborate on the durability of paper money stored in a safe? I'm curious about the factors that might affect its longevity, such as the humidity, temperature, and the quality of the paper itself. Does the type of safe matter? Should I consider vacuum sealing the currency for extra protection? Also, how do banknotes from different countries vary in terms of their resilience to aging? I'm interested in understanding the best practices for preserving paper money for the long term.
