Yet another obscenely overpriced example from this seller who speciously purports to be "an expert, enthusiast, author and trusted dealer in numismatic coins", which also begs the question, what other sorts of coin are there? Furthermore, in the FAQ section of his eBay pages he claims to be "world-renowned"! This is full-blown cringing material!
Even in unclipped condition, this Calais groat would be worth far less than a tenth of the asking price!
