6. Music – CDs and Vinyl
It’s well-known that vinyl has returned to the market and CDs are also expected to have the same growth in a short period of time. Music and movies are available to buy really easy online in digital form, so publishers aren’t as focused on physical copies, which is why the price of originals are more and more expensive. The older the copy, the higher the price is likely to be. If you scour the internet or small shops thoroughly enough, you’re sure to find great investments.
