Argentum
Argentum Sans is forked from the font Montserrat, version 5.001. The changes are adding a tail on lowercase 'l', a more traditional 'G', and duplexed tabular numerals.
Argentum Sans is a 'revival of a revival', as the Montserrat font suffered two major changes in 2017; as a response, this project was born in January 2018.
