All coins carry the 1957 date. The interesting part is the small star on the reverse side of the coin. It contains two numbers, and certain coins with certain numbers are quite rare. You need a magnifier to clearly see the starred numbers. On some coins the star is replaced by the letters BA, and these, also, are rare.
The list below gives approximate catalog values for special coins that have star numbers as listed. Values quoted are for coins in well preserved condition.
star numbers 58, 61, 66: $3
star number 63: $15
