When it comes to liquidity, both 1-gram and 1-ounce gold bars have distinct advantages and disadvantages. The primary difference lies in their market appeal and the target audience for each size.

That means for a 1-ounce gold bar valued at about $2,700 currently, investors might expect to pay anywhere from $27 to $54 per year in insurance premiums.

As of June 2, 2025, the Rand Refinery 1-ounce bar is listed at $3,369.99, while the PAMP Suisse version is priced at $3,389.99. That marks a 73% and 71% increase, respectively, in less than two years.

So while 1-ounce gold bars may be more cost-effective than buying coins, if you have a lot of capital you may be better off buying a larger bar instead — as long as you have the storage for it.
