I bought about $120K of physical Gold and Silver bullion, junk silver and semi-numismatic coins in 2016-17, both as part of a diversified portfolio but also as part of my SHTF strategy. Other investors I respected held 5-10% of their portfolios in PM, so it seemed safe despite all the additional hype.
Since them, I've sold some of the silver and a small part of the gold but still have around the same amount as when I started value-wise. I'm glad to see the premiums going up; I wish the prices would go up some more too. I don't plan on buying any more, and will just save it for emergencies. Now is not the time to divest.
I wouldn't recommend PM as an investment - more as a hedge; although over the long run, it will always hold its value. The bid/ask transaction costs take a chunk out of the value, but PM is surprisingly fungible. If I had invested the money somewhere else, I'd probably have more digits, but I like the comfort of having it close at hand.
This is a long-term hedge. After a year or two, I regretted buying PM - I was losing money selling. After 6 or 7 years, I don't regret it, but I would do it differently next time. I went 60/40 silver/gold, but if I had to do it again, I'd go 20/80 silver/gold and only buy bullion U.S. and Canadian coins and a bit of junk silver. There's definitely a learning curve, and a lot of shiny products to choose from. Unless you are a collector, keeping it simple and straightforward is my best advice.
