Saw an auction for a sealed graded cassette copy of Public Enemy’s 1990 album “Fear of a Black Planet”. Music grading is very new and both the concept of grading and the company that graded this, Rewind Grading, might end up being a home run or a bust. Who knows. All I know is when I was thumbing my nose at cassette tapes in Sam Goody two decades ago, I never would’ve thought I’d drop a C-note on one someday.
