'A scrappy and summary list of coins survives, entitled ‘Catalogue of the Lady Carteret’. This must be John Carteret’s mother selling the collection ‘during his minority’ (see FINA 14448). The relevant pages consist of a summary bill, dated 22 April 1704, and with various bits of arithmetic. It shows that the collection was very large, almost 6000 pieces. The document shows the purchase of 5803 coins and medals at a total price of £669 6s 0d.' (Burnett 2020b, pp. 376-7)
