In 2000 were issued 6 more coins specifically rather than loosely dedicated to the 2004 Games.
The values were 500 Drachma and they were Cupronickel rather than silver like previous coins at this value. Inflation had made this value worth just a couple of dollars each by 2000. Although commems, they did circulate until 2002 with the change to Euros and they minted 4 million of each coin, a lot in a country with 10 million people.

All 6 coins showed the same obverse with Games Logo, date and face value.

The other side had a different image for each coin.
