Mint (M) is the highest grade in the Goldmine record grading standard, describing a record in absolutely perfect condition. A Mint record shows no signs of handling, wear, or play. The vinyl surface is flawless — no scratches, scuffs, or fingerprints. The cover, inner sleeve, and any inserts are equally pristine. In practice, only sealed and unplayed records qualify as truly Mint.
Near Mint (NM or M-) is the grade most commonly used for excellent-condition records that have been opened and possibly played but show no visible signs of wear. This is the practical ceiling for used records, as even careful handling introduces microscopic signs. Most collectors consider NM the target condition for serious purchases.
Condition dramatically affects value. For a common album, the difference between VG+ and NM might be $5-15. For a rare first pressing, the same condition jump can mean hundreds or thousands of dollars. Always store your records properly — in anti-static inner sleeves, upright (never stacked), in a climate-controlled environment — to maintain the best possible condition over time.
Record sellers who grade every item as "Mint" are a red flag — experienced collectors know that truly Mint used records are exceptionally rare.
