Stuart, the seller clearly knows what they're talking about. Her response to an innocent question by an 'unsuspecting' eBayer was as follows: "ive had this coin since my dad passed away in 1996 he was a collector ,,had it valued ,, its worth a lot more but I thought ide start auction low ,,its exact coin to ths one ,,,thanks for intrest ,,,ebay id 260642742187 " Great. So it's now a countermarked 'sixpence', too. Perfect.
