The one-ounce gold bar is the workhorse of private bullion ownership: substantial, widely recognized, compact and easier to resell in increments than a 10 oz bar.
Why one ounce is the core size
One ounce is large enough to keep fabrication premiums reasonable while remaining a practical resale unit. It is also an easy format for comparing bars with government-minted one-ounce coins.
Assay cards and serial numbers
Many minted bars arrive sealed with assay information and a serial number. The packaging can help with identification and presentation, but the dealer and refiner reputation still matter.
Recognized refiners
Common names include PAMP, Valcambi, Argor-Heraeus, Perth Mint, Royal Canadian Mint and other accredited refiners. Brand recognition can help resale, but do not pay a huge premium for a decorative design if your goal is metal weight.
Random or assorted bars
Assorted inventory can reduce the premium. The dealer chooses a qualifying bar based on stock, so the design and refiner may vary. This is useful for weight-first buyers and less suitable for someone building a matched set.
Coins versus bars
A bar may be cheaper per ounce. A sovereign coin can be more familiar to local buyers and often has stronger visual appeal. Compare actual dealer buyback spreads before deciding.

Investment bars are commonly .9999 or .999 fine, but always read the product specification and markings.
Is an assay card necessary?

Are gold coins easier to sell?
Major sovereign coins may be more instantly recognizable, while well-known bars are also widely traded. Local preferences vary.
