The detectorist who unearthed this coin asked to remain anonymous. Someone in his club believed this find might be significant so I was asked to provide an ID and a valuation.
The coin is an Irish penny of Edward IV, which was struck at the mint situated in Dublin. On the obverse there is a saltire at each side of the king’s neck. On the reverse the legend reads CIVI TAS DVB LIn.
This coin was struck at Dublin during the heavy coinage of Edward IV. In Coins of Scotland Ireland and the Islands this type is listed as number 6311C.
The coin is short of flan but most Irish pennies of Edward IV display the same defect. However, it would grade about VF for the issue and is an extremely rare variety.
Over recent years a high number of Irish pennies of Edward IV have come onto the market. In some cases this has had a downward impact on sale prices. An example of this type was sold at auction early in 2017 with a pre-sale estimate of £240-300 but the hammer price was only £150. The coin pictured here should sell for at least the same figure but it is well below the catalogue price. If it was offered for sale then a private collector would be likely to pay a higher price than the coin would achieve if sold at auction.
