It has come to our attention that some of the reference numbers cited on earlier UKDFD records have been rendered obsolete as a result of publishers making changes in later editions of their catalogues. This is particularly the case with the Spink Standard Catalogue of British Coins, new editions of which are usually published annually.

For this reason, future citations of Spink coin numbers referenced on our database records will include the year of the edition to which they refer, e.g. Spink (2024) 777A. It is not practicable to review all database records retrospectively, but we will update any individual records brought to our attention by recorders or database users.
