1827 O-136 R4 Capped Bust Half Dollar

Obverse: 23
Reverse: AB (Second Marriage)
Available in grades up to MS66, with a decent population of AU's for an R4. The early die state with the 8 in the dentils is actually very rare and may be an R6. 

NGC Graded XF45. Original gray dirt coin struck from very worn dies. Milling is completely gone and the "8" punched below the date is lapped off.
