This is another coin from the collection of detecting finds built up by John Lashmar. It’s a voided short cross penny of King John.
On the obverse the portrait of John stands out well but the legend is flat or weak in a number of places. However, enough detail is visible for me to say this penny belongs to class Vc (number 1352 in the Standard Catalogue).
The reverse also has flat areas but I managed to read the legend as +LVKAS ON WINC. Therefore, the moneyer is Lukas and the mint Winchester.
On the plus side, pennies from the Winchester mint are not as common as those struck at London and Canterbury. On the minus side, the overall state of preservation isn’t particularly good. In its present condition my price range would be £30 – £40.
