Platinum IRA for a Gold guy? Tax implications and dealer recs

Alright, so I’m finally biting the bullet and looking to diversify a chunk into precious metals beyond my usual gold plays. Usually, it's just physical gold bullion, some GLD, a little GDX if I'm feeling spunky. But with the market being… interesting, and frankly, my exposure already heavily skewed to equities and a few niche funds, I've been seriously looking at a Platinum IRA. I'm talking a pretty substantial allocation here, thinking somewhere in the low seven figures to start, potentially scaling up to 5-10% of my overall liquid-ish portfolio within the next year or two, depending on how things shake out. This would be a new account, distinct from my existing traditional and Roth IRAs.

My concern isn't really the metals themselves – I get the long-term inflation hedge, the geopolitical buffer, all that good stuff. What I’m really trying to get my head around are the specific tax implications for platinum vs. gold within an IRA structure. Is there anything sneaky I need to be aware of that's different? I know the general IRA rules inside and out for stocks/bonds, but the physical metals aspect adds a layer I'm less familiar with. Custodianship, storage fees, potential complications down the line when it comes to distributions – any war stories or critical best practices here from anyone who’s done a significant Platinum IRA setup?

Also, dealer recommendations are huge. I’m in Greenwich, CT, so proximity isn't a primary concern as I'm used to dealing with folks remotely for a lot of my investments, but reputation and transparency are paramount. I need a dealer who understands the stakes, isn’t going to play games with premiums, and has a rock-solid process for IRA-eligible platinum coins/bars. I’ve heard horror stories about some of the more aggressive marketers, and frankly, I don't have the time or patience for that. Is there a "go-to" for this specific kind of play?

Thinking about allocating maybe $1.5M - $2M initially into platinum, alongside a similar amount into gold I already hold. Any advice from those who've navigated a large-scale precious metals IRA, especially with platinum, would be greatly appreciated.
