Human Factors
While working Radar West a C-130 came off of LRF requesting direct to HERCK intersection to hold. I misread the approach plate with the holding procedures and issued an altitude of 2000'. The hold at HERCK is depicted at 3000'. The aircraft entered a 2200' MVA while holding at 2000'. I noticed the MVA as they entered it and immediately climbed them to 2200'.
Controller reported issuing a holding altitude below the minimum vectoring altitude: once realized; a new and higher altitude was issued.
