1808 O-106 R2 Capped Bust Half Dollar

Obverse: 6
Reverse: F
O-106 R2 below and O-106a R2 at bottom

There have only been 4 problem free AU appearances for O-106 (prime state) the last ten years. This was updated 05/03/2016, and I have not seen any new AU appearances so the 5 was reduced to 4. Keep your eyes peeled!
This die state (a) of O-106 has had only 2 problem free MS and 5 problem free AU appearances in the market the last 10 years, combined with only 5 AU early die state appearances making this one particularly tough in higher grades.
