Premium falls as the bar gets bigger
A refiner spends roughly the same on assay, packaging and handling whether a bar holds one gram or one kilogram. That fixed cost is spread across the metal, so the percentage you pay over melt drops steeply with size - often above 20% on a one-gram bar and low single digits on a kilo.
The trade-off is divisibility. A kilo bar has to be sold whole, so a holding split across several 100 gram bars can be sold in stages while a single large bar cannot. Cheapest per gram and easiest to sell are not the same objective.
Cast, minted, and the assay card
Small bars are usually minted - struck from rolled sheet, sharp-edged, and sealed in a tamper-evident assay card that carries the serial number. Large bars are usually cast: poured into a mould, rougher, with the details stamped afterwards.
Breaking a minted bar out of its assay card can cost you at resale, because the card is what lets the next buyer accept the weight and purity without testing. Leave it sealed.
