When was the euro introduced as legal currency on the world market?

Evie, it's only confusing because there's a difference of when it became tradable on the markets, which was what the question asked and that was 1999, versus when people were able to use the notes and coins which was 2002. People will remember the 2002 date because that's when it became tangible but it was legally tradable in 1999.

Slightly confusing question. I went for the date the currency actually entered the market.

Very tricky question. Since I don’t have access to financial inners, I answered when the actual currency started changing hands.

is their old money still good?

Player #326446, that will never happen!! America likes to be different and would be too expensive. They may have to make the change!!
