# Newton becomes Master of the Mint

Date: 1699

## The fact

At Christmas 1699 Newton became Master of the Mint, the senior profitable office, and held it for the rest of his life. It is not the Warden's oath of 1696. Isaac Newton's documented role is: He took the Master's profitable office and held it until death. The Crown appointed; clerks struck coin.

## Context

Thomas Neale died. The Mastership paid. Newton had already moved to London. Sharing striking with unnamed moneyers is required. The setting of Newton becomes Master of the Mint is the public file around 1699-12-25. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Contribution type is direct. Driver [fiscal-policy-sustainability](/drivers/fiscal-policy-sustainability) is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

The contribution type is direct. The attached driver is fiscal-policy-sustainability. The welfare reading used in this dossier is worsening. That reading is an impact-path choice, not a property stored on the Fact itself.
