1897M half sovereigns in Murdoch collection

[Mr T]

Does anyone happen to have a catalogue of the Murdoch Collection from 1903-1904 handy? I saw on another site that three 1897M half sovereigns were financed by and struck for John G. Murdoch but no citation was given. I assume the auction catalogue is the source of this information but I couldn't find an accessible version online (I think there was a link available only in the USA).

I tracked down the catalogue in question: https://nnp.wustl.edu/library/auctionlots?AucCoId=511728&AuctionId=525399

But it makes no reference (that I can easily see) of Murdoch arranging to have the coin struck for him.
