Buying a 100 grams product
A 100 g bar is about 3.22 troy ounces. Ask for both a purchase quote and a same-day buyback quote to understand the spread before committing. The quoted weight needs a convention: a bar may state gross weight and fineness, while a bullion coin may advertise a fine-metal content. Check the refiner or mint specification. This page separates pure fine-gold weight from a same-weight 999 alloy so the small purity difference is visible rather than hidden in rounding.
How the spot reference is calculated
The fine-metal price is the current USD ounce quote divided by 31.1034768 grams, multiplied by 100. For a gross-weight product, apply its actual fineness once. At this weight, a 1% price movement changes the fine-gold reference by USD 134.59. That is a sensitivity example, not a forecast. Values are rounded for display only; the calculation retains full precision.
Compare delivered cost and the buyback spread
A dealer's offer includes fabrication, distribution and margin, and can include delivery and transaction-specific taxes. Calculate the premium against the matching metal reference, with the same weight, fineness, currency and quote time. Ask for a buyback quote for the exact product as well as its sale price. The difference tells you more about a round trip than a headline premium alone. Packaging, verification and brand recognition can affect the dealer's terms without changing spot.
If your 100 grams item is jewelry
Do not apply the pure-gold value to the full weight of a 14K ring or 18K chain. A net 100 g 18K alloy has 75 g of fine gold before stones and non-gold parts are considered. The calculator below starts at this weight and 24K (999); switch to the item's grade. An assay can be more precise than a nominal karat fraction. Preserve possible brand, antique or gemstone resale value before treating jewelry as scrap.
Storage, records and freshness
Keep the invoice, product specification and authenticity records with a secure inventory. Confirm insurance explicitly covers bullion rather than assuming ordinary parcel or household coverage applies. Local taxes vary by jurisdiction and product; no global tax exemption is assumed. Live observations are cached for five minutes and may remain visible while refreshing. Read the quote timestamp before using the table to negotiate, and use the historical chart for context rather than predicting the best day to buy.
