Seven-inch records, or 45s, were first introduced in the late 40s by the RCA Victor record label. The 45 record was made to be the rival of the 33, or 12-inch long playing record. It is called a 45 because it plays at 45 RPM's, or revolutions per minute on a turntable. 45 records have become boutique collectible items for record collectors everywhere. However, many record collector's are not sure how to price their seven-inch record collection. According to GoContinental.com, many record collectors wrongly assume the determining factor of value is a record's age, which is almost never the case. The worth of any record is largely dependent upon its popularity, and the musical era during which it was released.
