I think it includes everything Pausanias saw on his grand tour, organized by city. He wrote in the late second century AD. I don't know where Apollo Sauroktonos was in antiquity and have not looked hard enough to know if it is in there.
Another one was sold in 2017. I also checked RPC online and 4 specimen are reported, sadly without any pictures.
I think this is the one @Ocatarinetabellatchitchix is referring to. The auctioneer notes, "Das Motiv des schlafenden Hermaphroditen ist durch eine Skulptur im Pariser Louvre überliefert."
The book Ancient coins Illustrating Lost Masterpieces of Ancient Art: A numismatic Commentary on Pausanias was an attempt to bring to a 1960s audience three very old journal articles. It is not organized by modern standards and is tough going if you didn't learn lower-case polytonic Greek at your 19th century English boarding school. The original articles are located at https://archive.org/details/journalofhelleni06soci/page/50 https://archive.org/details/journalofhelleni07sociuoft/page/57 https://archive.org/details/journalofhelleni08soci/page/6 It would be a worthy project to bring this scholarship to a modern numismatic audience.
@dougsmit , I don't think he excludes statues that are still extant. Most are lost, so the title is dramatic, but not fully descriptive.
