Released in circulation date

Every banknote has an exact date when it was released in circulation. Not only the type of banknotes, also every different year.
For example Yugoslavia 5000 dinara 1963 has the date 1st May 1963 written on the banknote but it was released in circulation later on 15th September 1964. Some banknotes has been released in circulation few years later than the date written on the banknote.

I suggest to add a field for that information. It is very usefull for numismatic researches.

To add that field just for a specific type of banknote when that type was released in circulation first time.
Before the date of "released from circulation (demonetized)".

We can add it also for every different year but my opinion is that is useless.

Just so long as we're clear that withdrawal from circulation and demonetization are two different things then this can only enhance the information recorded.

You have my vote. This feature would be useful for coins, especially NCLT.

I would welcome this feature as above
