Dublin, OH investor here: Silver bars for recession-proofing - anyone else?

• •Living here in Dublin, OH, things have been good, but honestly, the economic rumblings lately are making me a bit antsy.
• •I’m talking about all the inflation talk, interest rate hikes, and general geopolitical chaos.
• •It’s got me seriously thinking about how to truly recession-proof what I’ve got, especially since I'm trying to set up my kids for the future.

Okay, so I’ve been sitting on a decent chunk of change since I cashed out my tech startup a couple of years back – think somewhere in the low 7-figures, maybe $4-$5 million after taxes. Living here in Dublin, OH, things have been good, but honestly, the economic rumblings lately are making me a bit antsy. I’m talking about all the inflation talk, interest rate hikes, and general geopolitical chaos. It’s got me seriously thinking about how to truly recession-proof what I’ve got, especially since I'm trying to set up my kids for the future.

I dove deep into research, and silver bars keep popping up as a strong contender. I know a lot of people go straight for gold, and I’ve got some of that too, but silver’s lower entry point and industrial demand appeal to me. I’m looking at physical bars, held in a segregated vault by a reputable third-party custodian. Not really interested in ETFs or mining stocks for this specific purpose; I prefer the tangible asset. The thought is that if the traditional markets take a nosedive, having actual silver could act as a hedge.

My main concern is the liquidity if I ever need to offload a significant amount quickly. Has anyone here had experience selling a substantial amount of silver bars during an economic downturn? What was that process like? Did you get a fair market price, or did you take a hit? Also, for those of you who’ve gone this route, what percentage of your total portfolio do you feel comfortable allocating to precious metals, specifically silver, for this kind of "recession-proof" strategy? I'm leaning towards around 10-15% of my total, but curious to hear other perspectives. Any insights from fellow investors, especially those who’ve been through a few economic cycles, would be incredibly valuable.
