The album debuted and peaked at number 7 on the Billboard 200, with 118,000 units sold in its first week.[1] The album was certified Gold by the RIAA on September 14, 1999, for shipments and sales of over 500,000 units in America.
Matt Diehl of Entertainment Weekly praised Bleek for holding his own lyrically alongside guest artists Ja Rule and N.O.R.E., and displaying striking sensitivity on "Regular Cat". He also noted how the album's production of "ominous inner-city symphonies and raw street beats" was ageless.[3] Keith Farley from AllMusic noted how Bleek's vocal delivery was more "street-level" than Jay-Z's, along with the album containing an "urban funk" style like most of his material, concluding that "Still, Coming of Age is a fine debut that shows Memphis Bleek already leaps and bounds ahead of most rappers."[2] In a dual review with Ja's Venni Vetti Vecci, Rolling Stone's Rob Sheffield felt that Bleek came across as a cliché-filled rapper that lacked witticism in his lyrics and wasted the beats given to him by his producers.[4]
