I have collected records for over 50 years. I am now in the process of selling them off. Grading vinyl records is a very subjective perception. People will sell beat scratched records for the price of a record that is Ex or Near Mint.  About 8 years ago I started reading about coins, world coins and then exclusively US Coins. Grading was always important to me when dealing with vinyl, especially when you buy at flea markets, yards sales and thrift stores or used record stores or record shows or record fairs. It simply does not matter if you are buying used vinyl grading is subjective. I tend to be on the strict end. 

As I read more about coin collecting, I read that coin grading is very subjective as well. It was then I decide I would learn more and start selling coins. At the time my wife happened to be working in a small local diner where nearly all the meals were paid for with cash so she brought home a lot of change. The more I read about coins I realized that error coins was a good way to start looking for coins to collect to sell. 

For the most part I have just collected coins. However I have had some excellent results selling error coins. With the highlights being, a dime for $100.00, it was missing part of the clad layer and was under weight. $80.00 for a dime that was what appeared to be damage from the mint but I was not sure and sold it as an unknown error. I sold a some others but most were for much less.

I loved the hunt for vinyl records. I remember my favorite part of collecting was buying records by artist I had never heard of, or had heard of but never seen any vinyl lp's by them. 

This is  how I learned of Hawkwind, Man, Can, Sir Douglas Quintet, Eric Quincy Tate, Hydra, Amon Duul II, Ash Ra Temple, Laurie Anderson, Becky Hobbs and on and on over the years.  I passed on beat scratched copies of records in favor of a ex or nm or sealed copy. 

This I have found coin collecting the same way. I enjoy looking through coins trying to find that scare print of a mint issue such as a "Close AM" or a obvious error. 

I only think of crypto as a hedge against the failure of the US Dollar, I don't collect every crypto, I simple have a few core assets and like any good record collector or coin collector I hold on to them
