Victoria (1837-1901), Threepence, 1853 (ESC 3384; S 3914). About mint state with reflective fields, a key date and extremely rare in any grade
£1,000-£1,200

The reflective fields would suggest that this specimen might be a possible proof strike. It is not a combination of maundy and currency issues, a pairing that is sometimes found with this date due to the demand for proof sets throughout the Victorian period and the need to find dies once older ones had worn out.
