There were no 1978 Olympics.

Both the summer and winter Olympics of that time were held in the same year, and every fourth year.

There were Olympic games in 1976 and 1980, but none in 1978.

yes

Argentina hosted the 1978 World Cup, and also won it, beating the Netherlands in the final.

I too thought I had a 1978 $2 bill. But after reading that there's no $2 bills printed in 1978, I got a magnifying glass and seen it is a 1976 but boy' did they not print that very clearly. Anyway, if your thinking you got a 1978 as I and others thought, check again. It's probably a 1976. Good luck.
