With the new state quarters, there are nine coins in a 1999 date collection!
It's a 1999 date collection—one of each coin the United States Mint made that year.
The number of coins needed for a date set changes.
For example, a complete 1998 date collection has five coins—not nine.
Why are there more coins in a 1999 set?
Because of the new 50 State Quarters™ Program!
