Only issuer- or exchange-documented coin variants appear in the selectors. Blank gross weights remain unavailable rather than inferred, and both values use the same current Gold quote.

Calculation method
How the result is calculated
Each coin's sourced fine-gold weight is converted to troy ounces if required, then multiplied by the same current Gold spot quote.
Theoretical melt values are not buy/sell prices. Coin authenticity, condition, collectible value, market premiums, taxes, and dealer spreads are outside this comparison.
