In the introduction to this article, we talked about the error that most people made when they threw away their entire vinyl collection to replace them with CDs. The news is about to get worse for some of those people, because if you then went on to throw out your CD collection to replace them with digital files and streams, you've probably repeated the same mistake and lost out on even more money!
If it's any consolation, your collection was probably only worth big money if you had rare CDs in it - early EPs by bands who went on to make it big, or first editions. The average CD still doesn't have a value of more than a couple of dollars (although who knows how much that will go up by in years to come). Limited edition or rare releases by big-name artists are where the big money is, as you might expect. Coldplay's first-ever EP 'Safety' from 1998 is worth $1,500.
