From Middle English mynt, münet (“money, coin”), from Old English mynet (“coin”), from late Proto-West Germanic *munit, from Latin monēta (“place for making coins, coined money”), from the temple of Juno Moneta (named for Monēta mother of the Muses), where coins were made. Doublet of money and manat. The verb is from the noun; Old English mynetian (“to mint”) is a parallel formation.
From Middle English mynte, from Old English minte (“mint plant”), from Proto-West Germanic *mintā (“mint”), from Latin menta, probably from a lost Mediterranean language either through Ancient Greek μίνθη (mínthē), μίνθα (míntha) or directly. Akin to Old Norse minta (“mint”). Doublet of mentha.
From Middle English minten, from Old English myntan (“to mean, intend, purpose, determine, resolve”), from Proto-West Germanic muntijan (“to think, consider”), from Proto-Indo-European men-, *mnā- (“to think”). Cognate with Saterland Frisian mintsje, muntsje (“to aim, target”), Dutch munten (“to aim at, target”), German Low German münten (“to aim at”), German münzen (“to aim at”), Dutch monter (“cheerful, gladsome, spry”), Gothic 𐌼𐌿𐌽𐍃 (muns, “thought, opinion”), Old English munan (“to be mindful of, consider, intend”).

When referring to the place where coins are made, it is a standard countable noun; in the sense of 'a large amount of money', it is typically used in the singular with the indefinite article.
