Italian 1 € coin without "R" mark and "date" on the reverse

HI,

I just receive this coin after pay a coffe on a coffe shop, But I can't find on catalogue.

where can I registered?

Welcome to numista.

You're showing us a rather damaged coin, so any variant you might think of, is certainly caused by PMD (Post Mint Damage), sorry, but you didn't win in the lottery!

ok, what you're saying is that the coin has been intentionally altered, removing the year and the “r” mark?

No, just being extremely used, did it!

Well, I have a few Italian euro coins (I'm not a numismatic expert), but it's very, very difficult for that mark to disappear from a coin, just through use, also because the relief isn't uniform throughout the coin, don't you agree?

It's true that in portugal the most common italian coins are from 2002, but...

Thanks for the info, though!

So why did you ask? 

I'm asking because I want to find out more about the coin.

I found other similar cases of this Italian coin on the internet (on different numismatic sites), for example

In the meantime, I'll keep it separately, waiting for future similar cases.

thanks again

Just do not ask anymore, since your own judgment is pre-established. A loss of time for all! Fell free to use the other internet sites, as you wish. I'm not losing more time on this.
