Hershey’s Miniatures were originally packaged as an assortment in 1939, and featured the most popular Hershey chocolate bars of that time. The product currently contains traditional Hershey bars, Mr. Goodbars, Hershey's Special Dark, and Krackel bars. Krackel bars were now only available in this assortment. However, in 2014 they were reintroduced as stand alone bars.
Each Miniature weighs roughly 8.6g and contains 42 calories. 
A line extension called Hershey’s Miniatures Nut Lovers featuring four kinds of chocolate paired with four varieties of nuts was introduced in 2004 along with La Dulceria Thalia Hershey’s Miniatures, a cookie and candy assortment.
