Per "A Guide Book of United States Coins", 2011 (the latest copy I own), value is $8.00 each. However, there are a few sets in which the "S" mintmark is better struck (clearer), those are worth about $100.00. I can't tell from the photo whether you have the clearer mintmark. You can take them to any coin dealer and he'll tell you which sets you have.
This book is published each year (usually known as "The Red Book", the color of the cover), and lists average retail values of all U. S. coins. The value of this set is unlikely to have changed much since 2011.
