Your old vinyl record collection’s worth is dependent on the status of your old records. Also, you must take into account the artist,  year, title and record condition. Vinyl record grading is important when performing record valuation.
Play Grading is when you place the vinyl record on a turntable and listen very closely to the sound quality, watch for skipping and other sound defects. Visual Grading is when you use a particular light source at a short distance away from the record as you inspect it. Halogen and direct natural sunlight work best. After your vinyl record is inspected, it will receive a vinyl record grading from Mint condition to poor condition.
