Crawford indicates that the name of the moneyer is not completely certain, and there are no writings mentioning this particular Pinarius Natta, if that is his name, but that he is likely related to the Pinarius Natta who is thought to have minted a very similar issue(Crawford 208) in 149 BC, which only differs in a few small stylistic ways and also in its reverse legend being "NATA" as opposed to "NAT".
