Watch List notes:

William III (1694-1702), Exeter Halfcrown, 1697 NONO, 'A for V in TVTAMEN error', first laureate, draped and cuirassed bust right, E over B below, rev. crowned shields cruciform, large shields, ordinary harp with seven strings, six billets, lettered edge, 'error' A for V in TVTAMEN, 14.85g, 6h (Bull 1081; ESC 548C; Spink 3490), scarcely fine, but the variety presumed very rare.
The edge 'error' A for V in TVTAMEN is very uncertain here and supports the contention that it is a minor flaw and not a true 'error'.
Estimate: £80.00 - £120.00
