It is doubtful that it was pierced so it could be worn as jewellery during Roman times, for lots of ready-made jewellery was available. Therefore, it could have been pierced during a later period. Leading on from this, were the coin reported then it might be classed as Treasure. Much would depend on other finds that have been unearthed on the same site. For example, if the site has given up a range of items dating from the early Anglo-Saxon period – a time when coins were pierced to be worn as jewellery. To be on the safe side, the best route forward would be to report this find as possible Treasure.
