Louis-Philippe's accession in August 1830 following the July Revolution created an immediate problem for the Paris Mint: the old Bourbon coinage bearing Charles X's portrait had to be replaced with minimal disruption to commerce. Pierre-Joseph Tiolier, who had served as chief engraver since 1816, cut the new dies before dying in office in late 1830 — his son Nicolas-Pierre completed the transition. The raised-edge variety is distinguished from the plain-edge and lettered-edge strikings produced concurrently, a short-lived characteristic of this first emission before the specification was standardized.
