Gold IRA storage fees - what's considered reasonable these days?

• •I've got a little over $300k in physical gold and silver allocated, and my current custodian charges a flat annual fee of $250.
• •I'm a doctor here in Boston, so my time is pretty locked up, and I haven't done a deep dive into comparing custodians in a while.
• •But $250 for a roughly $300k holding, even for segregated, feels like it *might* be on the higher end now.

I've been holding a portion of my retirement savings in a Gold IRA for about 8 years now, and the physical storage fees have always been a low-key annoyance, but I'm starting to wonder if what I'm paying is still competitive. I've got a little over $300k in physical gold and silver allocated, and my current custodian charges a flat annual fee of $250. It's not a huge bite out of the overall value, but when you look at it purely as a percentage, especially with gold seeing some good runs lately, it feels a bit… stagnant.

I'm a doctor here in Boston, so my time is pretty locked up, and I haven't done a deep dive into comparing custodians in a while. My initial research back when I set this up revolved around finding a reputable company with segregated storage, which they do provide, and I liked their insurance policies. But $250 for a roughly $300k holding, even for segregated, feels like it might be on the higher end now. Or am I just becoming more sensitive to every penny in my portfolio? I remember seeing some percentage-based fees back then too, which I avoided because of how they can scale up.

For those of you with Gold IRAs, especially on the larger side (say, $200k+), what are you currently paying for physical storage? Flat fee, or percentage? Any custodians you've had particularly good or bad experiences with in terms of transparency or fee structure? Just trying to gauge if it's worth the hassle of potentially looking into a transfer, or if my current arrangement is still pretty standard. Thanks for any insights!
