Problem with the Euro period for different countries

I have seen that, for example, the Euro period for Estonia is 2002- today but this is not correct, since Estonia adopted Euro in 2011.
I think that the Euro period is not to be obliged to be the same for all the countries, it should be in accord with the precise time the Euro was adopted.

Kind regards

I agree with you there,Gianna.

Cyprus & Malta both changed over to the Euro in 2008.

Lithuania changed to the Euro in 2015.

This is because those coins technically (on Numista) share one currency.
