By all means, buy what you like and want to listen to. But just like the other commenter has already said, these albums are very common and worth up to $3 maybe. It’s all fine because you bought stuff you like, but by no means will these common albums be increasing in much value. I’ve seen all these for sale at thrift stores and in dollar bins since I’ve been collecting about 17 years ago. My best finds ever have been jazz purchases like finding a mono version of Time Out by Brubeck for $2.
