Seriously, how much does coin grading *actually* matter for a Gold IRA? (Talking rounds, not coins)

• •Okay, so I've been a pretty consistent investor in gold for my IRA over the last few years – mostly looking at physical gold, obviously.
• •I'm sitting on about $180k invested in precious metals right now, a good chunk of that being various gold rounds.
• •I’m a healthcare administrator here in Tampa, so I’m all about steady, reliable growth and hedging against inflation, which gold definitely provides.

Okay, so I've been a pretty consistent investor in gold for my IRA over the last few years – mostly looking at physical gold, obviously. I'm sitting on about $180k invested in precious metals right now, a good chunk of that being various gold rounds. I’m a healthcare administrator here in Tampa, so I’m all about steady, reliable growth and hedging against inflation, which gold definitely provides.

My question is about grading, specifically for gold rounds that I'm holding in my IRA. I know for numismatic coins, grading is EVERYTHING. A MS70 coin can be worth multiples of an MS69. But for simple gold rounds, like the ones I've been buying – think generic 1oz or 1/2oz .999+ fine gold rounds from reputable mints – how much does the grading really impact the value when it comes to selling or taking distributions? I've mostly just ensured they're in good condition, no obvious scratches or damage, and always from sources sanctioned for IRA investing. I'm not collecting for numismatic value here, strictly for the gold content.

I ask because I’ve been offered graded rounds before, sometimes at a slight premium, and I've always just said no, figuring it was unnecessary for something that's essentially valued on its melt weight. Am I leaving money on the table here, or am I right to stick to the basics for IRA purposes? I’m thinking long-term here, probably looking to start taking distributions in the next 10-15 years when I hit retirement age. Also, on a related note, anyone have good resources for figuring out the tax implications of different types of distributions? I stumbled across a Tax Calculator tool the other day which seemed pretty neat for figuring out potential tax burdens, but I'm always looking for more intel on that front too.

Would love to hear from others who have gone through this, especially those who primarily hold rounds or bars in their Gold IRA. Is there any scenario where a graded round (purely for its metal content, not collector value) would fetch a significantly better price over an ungraded but identical round, assuming both are authenticated and in solid condition? Or is it truly just paying extra for a plastic slab and a piece of paper?
