This find was sent in by Damon Ward, who asked for a full ID and a valuation. It’s a coin of Elizabeth I and at 20mm in diameter it must be a threepence. In the case of coins of Elizabeth I it is important to give the diameter, as different denominations share the same design.
On the reverse this threepence is dated 1563 and on both sides the mint mark is a pheon. The date is quite scarce, so it would be of interest to a collector.
The bust on the obverse would grade only Fair but the rest of the coin is Fine. It has been centrally struck on a round flan, both of which are plus points. As 1563 is a scarce date this threepence should be worth £25 – £30 to a Tudor specialist.
