Many of the albums sold during the 1970s and early 1980s sold millions of copies when they were first released, and as a result it is difficult to find records that are in nice, playable condition. Because of that, it is unlikely that such records will bring in a lot of money from collectors.
Some records are valuable, but many people are unaware of what records they are valuable and why people are looking for them.
It is difficult to determine exactly what vinyl records are worth, and there are a number of different factors that determine whether a given record is worth a lot of money or is just a place mat.
