Outstanding, thank you Andrew. It is in fact specific coin from the list.
Just be aware that Ted Buttrey at the Fitzwilliam has no resources other than himself, neither staff nor money. He's usually very happy to answer these single references requests but in the case of repeated or extensive requests, he might suggest you visit in person or a donation to support catalogue purchasing, stationery etc may be appreciated. This is the same Ted Buttrey who excavated Morgantina in the 1950s so he is not as fast on his feet as he used to be.
All the Fitzwilliam's catalogue and fixed price lists are listed in a pdf directory on the Fitzwilliam website, so that should be the first place to look with a related query.
They have the largest collection in the world. The coverage is near 100% on auction catalogues, rather less on fixed price lists.
