[citation needed] This he received and he was soon appointed gastald of Conza, while his sons—Landenulf, Landulf, Indulf, and Guaimar—were invested with land in Salerno.
The Chronicon Salernitanum, which is the most important source for Landulf's life, names the counties of Marsi, Sarno, and Lauro as those of Guaimar, Indulf, and Landenulf, respectively, but does not name a county for Landulf.
Despite the brevity of his reign, Landulf appears to have succeeded in minting coins in Salerno.
One denarius weighing .66g survives bearing the legend +LAN / SALRN (in two lines, with LR ligatured).
[4] If the attribution of the denarius to Landulf is correct, he would be the first Salernitan ruler to mint them since Guaimar I before 900.
