Bullion is precious metal — gold, silver, platinum, palladium — valued on its weight and purity, not on collector claims or mint-state grading. The price you pay is the current spot price plus a small amount over spot that covers striking, shipping, and the dealer’s margin. On resale, you receive close to spot, less a small buyback difference.

Most long-view buyers begin with sovereign coins for their worldwide recognition and add bars as the holding grows. That order of operations keeps the early purchases easy to sell and the later purchases efficient on cost per ounce.

Both coins and bars hold the same underlying metal. The choice comes down to whether you want the fastest resale or the lowest outlay per ounce. Bullion coins from sovereign mints — American Eagles, Canadian Maple Leafs, Austrian Philharmonics — carry government-backed weight and purity, serve as legal tender in their home country, and move quickly on resale at any serious dealer. No assay needed. Most major coins clear the IRS bar for retirement accounts. The amount over spot runs about 3 to 8 percent.

Bullion bars from approved refiners — PAMP Suisse, Valcambi, Royal Canadian Mint — hold more metal for the dollar and stack tightly for storage. The amount over spot runs lower, around 1 to 3 percent. On resale, a bar may require a brief assay or verification, so the buyer pool is slightly narrower. Bars from approved refiners also clear the IRS bar for retirement accounts.

Start with coins for the worldwide recognition. Add bars when the holding grows and the cost per ounce starts to matter.

Most holdings we help build end up with both. Coins carry the early purchases and the easy resale. Bars carry the later purchases and the better cost per ounce. That pairing isn’t a rule, but it’s what a thoughtful position looks like over the years.

Sovereign mints — the U.S. Mint, Royal Canadian Mint, Perth Mint, Austrian Mint — back their products with government guarantees on weight and purity. Their coins carry legal tender status in the home country and are recognized on sight by any serious dealer worldwide. They also carry the most advanced anti-counterfeiting work on the market. The amount over spot is a little higher because of all of the above.

Private refiners — PAMP Suisse, Valcambi, Engelhard — strike bars and some rounds at lower amounts over spot. Quality varies by the reputation of the refiner, so the list of names that belong in a serious portfolio is shorter than the list of names on the market. Bars from approved refiners handle cleanly on resale and clear the IRS bar for retirement accounts.

Some products carry an amount over spot you will never see again on resale. The common pattern is a coin sold as “rare,” “collector grade,” or “mint error” at 40 to 100 percent above the melt value of its metal. On resale, most dealers pay melt. That difference is lost, not invested. It will not come back.

Watch for the usual signs: language like “limited edition” or “rare mint error,” amounts above 15 to 20 percent over spot for standard bullion, high- pressure calls, claims about guaranteed future value, graded coins sold at inflated prices, and products from mints or refiners without a standing name in the market. If a coin is pitched to you on its story rather than its weight and purity, the story is the price — and the story doesn’t hold value.

If you collect coins as a hobby, that’s a separate trade. Numismatics has its own merit and its own record. It isn’t a way to hold metal for the long view. For a retirement account or a preservation position, stay with bullion at small amounts over spot. See the IRA-eligible products sheet for the full list the IRS allows inside a retirement account.
