Watch List notes:

Halfcrown 1686 SECVNDO edge with V over S in IACOBVS, overdate variety as ESC 496A, Bull 752 with ESC 494, Bull 749 edge, NVG/VG with all major details clear. Our archive database shows 18 previous example of this date with the SECVNDO edge and none have the V over S in the obverse legend. All the previous V over S coins have had the TERTIO edge, online research of available coins has also not found the overstrike and SECVNDO edge on the same coin. We note the V over S for the correct TERTIO edge coin is rated at R3 by ESC and Bull. From this research and archival data presumably an extremely rare type, possibly R5 or rarer, and unrecorded as such by ESC or Bull.

Estimate: 120-200 GBP
