Here is an 1806 Draped Bust Quarter in VF25 in the B5 die marriage. The B5 die marriage is one of the tougher 1806 varieties and consider to be R4+ (76-118 extant) that carries about a 10% premium in both PCGS and CPG guides over the more common of the 9 die marriages for 1806 (6/5 B1 priced separately).  It is identified by Obverse 4 with a perfect T and Star 1 far from the bust, and Reverse G where Star 12 touches the Eagles Beak, amongst other die identifiers as documented in the Book - Early Quarter Dollars of the United Stats Mint 1796-1838 (Rea et al. 2010).    In either case, this die marriage is much harder to find than the R1-R3 marriages.  This example has a rich, light  russet and grey patina overlying its sliver surfaces with no detracting hits.  Certainly a wholesome and rare VF Draped Bust Quarter.
