Wow. I got out of coin and PM collecting (accumulating) about 30 years ago. About a month ago, decided to jump back in with the purchase of a 2017 1 ounce gold eagle from the US Mint. What I like - PM's don't require batteries, internet access, software upgrades, tech support. Just a good solid feeling in the hand.
What a beauty, I just bought five of the 1/10 ounces, I can't wait to see if I can get Ms-70 on all five.
You're right. Coins and PMs are a nice low-tech collectible. We can enhance the experience with Internet technology and photography and all that, but when you get right down to it, that's all optional. And gold is eternal.
