Storage Fees for Gold IRA - What's a decent rate?

Okay, so I've been looking into rolling a good chunk of my old 401k into a Gold IRA. I’ve got about $180k in there right now and honestly, with all the geopolitical garbage going on, I sleep better knowing some of that is in something tangible. I'm down here in Jacksonville, FL, and the whole idea of having some of my wealth outside the traditional financial system just feels more secure to me, especially with my background as a military contractor. I'm not looking to get rich quick, just preserve what I’ve got.

I’ve been getting quotes from a few different custodians and the storage fees are all over the place. One company just quoted me 0.5% of the total asset value annually for segregated storage, with a minimum of $200. Another one told me it was a flat $150 a year for up to $100k, then scaled after that. Then I've got one company telling me it's not a percentage at all, but rather a flat fee based on the number of bars/coins, which sounds kinda wild if you're holding a lot of smaller denominations.

My main concern is making sure the gold is actually held in a reputable, secure facility. I'm not skimping on security here, hence wanting segregated storage where my actual gold is accounted for, not just a proportional share of a commingled vault. I'm talking about a decent vault, hopefully insured up to the eyeballs just in case the absolute worst happens. Has anyone else gone through this process recently with a similar portfolio size (let's say $150k-$250k)?

What are you guys paying for segregated storage annually? Is a 0.5% AUM fee for segregated storage pretty standard, or am I getting fleeced? I feel like there's a lot of variability in this space and I want to make sure I’m not overpaying for what is essentially a glorified safety deposit box, albeit a very secure one. Any insights or recommendations on custodians would be much appreciated!
