S mint Indian Half Eagles still represent great value in this market. Depending on date, they range anywhere between 4 and 20 times more rare than their common date counterparts, but are only 2.5 to 4 times more expensive. The 13-S is not as rare as the very tough 08-S, but it is still a tougher date.
This original piece has some light abrasion but above average eye appeal with only the lightest wear. UNC coins of this date escalate in price quickly and AU58s are a great alternative.
