2 Euro Greece 2002 – Upside Down Inner Core? Rare Error?

Hello everyone,

I have a Greek 2 Euro coin from 2002 that appears to have a major minting error.

The inner core (with the national side, showing Europa on the bull) seems to have been inserted upside down before being pressed. When you hold the coin with the “2 EURO” side upright, the other side is flipped 180° — as if the center was placed backwards.

This does not look like simple rotation or wear. Both parts are aligned perfectly in terms of fit, but the inner core is reversed.

I’ve attached front and back images of the coin.

Could this be a known “inverted core” mint error?  
Is it rare or valuable?

Thank you very much for any input!

It is just a post-mint manipulation. albeit a rare one because of the difficulty. Someone popped out the core, reversed it, and pressed it back in.

This can't be a mint error, because core and rim are first joined together before the coin is struck. 

The inverted core minting error is as rare as the quartered €2 „Grace Kelly“ 2007 ¼ coin, both or all 4 corresponding pieces of the Grace Kelly €2 could be worth up to €50,000. I think the inverted core minting error on your coin will only get €200 euro cents on eBay though and maybe any quartered €2 coin (with all 4 pieces) could be worth more. Anyone who has the ¼ versions should post ASAP.

Hello, this happens regularly with two-euro and one-euro coins.
Some people have fun separating the center and putting it back together upside down.
Your change has no value, as it's damaged.

Sincerely,
