| Description | Separate books of account for Soho Mint were begun on 8 Feb. 1791. On 1 Oct. 1808 the principal books—Ledger, Journal, and Day Book—were again begun anew, apparently as a result of the transfer of the business into the name of Matthew Robinson Boulton. Some of the books are styled "Mint" books, others "Coinage" books, and others still "Mint and Coinage" books; the significance of these different names is not apparent. |
