"Brilliant uncirculated" (BU) refers to coins that have never been in circulation and exhibit no wear, often possessing a shiny, pristine appearance with full mint luster. "Mint state" (MS), on the other hand, is a grading term used to describe coins that are in the same condition as when they were minted, ranging from MS-60 (average) to MS-70 (perfect), with BU typically falling within this range. Essentially, BU is a subset of mint state coins, specifically highlighting their uncirculated and lustrous condition.
