Chas Gillard asked for a full ID and a valuation on this hammered silver coin, which is a London groat of Edward IV.
Edward became king in 1461 when Henry VI was deposed. Therefore, a Lancastrian was removed and a Yorkist took his place. After a fall out with the Earl of Warwick, in 1470 King Edward was removed and replaced by Henry VI. Edward was forced to flee overseas but in 1471 he was back and after a few battles he regained the throne.
This groat was struck during the second reign of Edward IV. It’s an example of type XIV with mint mark annulet on both sides.
The coin is slightly double struck on the reverse but is otherwise in about VF condition. As it stands, it should be worth close to £150 to a collector.
