I Know It Is A Hobby But...

And it's not just coins as I mentioned. Almost anything you collect as a hobby should really be your hobby, not an investment.
If and when you pass away, in many instances relatives have no or little idea of what you have and just basically dump it all for practically nothing.
A neighbor of mine in his 90's was recently taken to a place for it's time to go. (Hate to say dying). He collected model planes and his garage was virtually loaded with them. Many hundreds of them. His daughter called in a hobby store and they hauled the entire collection away for nothing. She just wanted it all out.
There are probably many such stories.
This too could have been coins, guns, knives, swords, cars or anything. So remember that this is supposed to be YOUR hobby, not YOUR investment or something for future relatives to just dump into a bank.

None of my relatives know anything about coins, so I would have to make a list of what I have (if I have any coins left at that time), and
put some websites, or something with proof of the coins' values, so coin dealers don't take advantage.

And, I also love holding a coin from 18?, and thinking who else held this coin......
