I have a good mix of things but personally I’m of the mindset I’d rather have basic plain old weight then collectable coins. I like basic bars or rounds like in this post above just generic sunshine mint rounds.

That said I do have a bunch of old coins 🪙 I just think to start it’s better to focus of the weight and just having the metal. As it grows then I’d mix it up. Just watch the premiums on any old coins. Fun to have and I have many odd collections I spent a huge premium on but I wish I kept it more basic.
