Only a very limited number of collectors own these popular issues minted in impressive proof quality. Each of the ten "short" sets offered in this 1999-2008 full collection feature five stunning proof quality S-mint issues with one year only engravings from the immensely popular Statehood Quarter series — that's 50 gorgeous proof coins that were never issued individually. The series followed each state's admission to the Union, from Delaware to Hawaii. Outer boxes may not be available on all sets.
