This is because the money for the elderly is the third set of currency with face value of 10 yuan issued by the state. However, because China has stopped circulating this denomination of currency, it also makes it impossible for banks to access this currency. This has caused difficulties for banks to some extent. Therefore, bank staff will choose to call the police and let the police solve such problems. Later, the police came to the bank and explained everything to the old man.

Since the third set of currency has long ceased to be issued, there is no possibility that the money in the hands of the elderly will be deposited in the bank. But now many people like to collect these ancient coins very much. Therefore, the currency of the elderly actually has a very high collection value, and the value that these currencies can generate is far higher than the value of the currency itself. So later, under the patient persuasion of the police, the old man decided to transfer these currencies to some collectors.

This incident actually tells us that we must deposit our money in the bank, and never wait until the money stops circulating before deciding to deposit it in the bank. This will make you encounter such trouble or be a little embarrassed. However, the old man has a ray of hope in every dark cloud, because the value of these currencies is very important, so it has also benefited the old man a lot. But this kind of behavior is not worth advocating, because it doesn't happen every time.

Its realization is that many people choose to collect this kind of currency, mainly because the historical significance and cultural value behind these currencies are very important. So a lot of money ended up as a collection. And because of the rise in market prices, the prices of these currencies have also risen.
