Nice complete set of the early half of Native American/Sacagawea dollar coins. All Uncirculated. These are the hard to get coins! It is normal for some of these uncirculated coins to have a little bit of coloration/toning in addition to some usual bag marks as well. 

P and D mint marks. Collection starts in 2000 and goes to 2008 when they started the new designed reverse (2009)
