"Records have value, and prices goes up in time for rare stuff, people with quality records are rich in a good way. It’s an investment."
That is true, but you have to sell it.
While investing in it, you may need to consider the market size for that rare stuff. There is a possibility that, as people age, there is less and less potential buyers of high-priced rarities.
If you do not sell it just at the right moment, at least while you are still alive, you may lose a large portion of your investment. As record collectors near the end their own life cycle, or cross over into eternity, more of the rare records may come to the market. Having less buyers and more rare records to be sold may not increase the price.
In short, if you want to get rich on records, sell them now.
If you are collecting them just to collect them because that is what makes you feel good, bring them on. Just do not convince yourself that you have something immensely valuable. No matter how rare your record collection is, you are not collecting dividends on them while you are staring at them at home.
