How to use a Canada gold hallmark lookup
A gold hallmark lookup Canada should help with a practical valuation problem. Before using a scrap gold calculator or asking for cash-for-gold quotes, you need to know whether an item is 10K, 18K, 22K or 24K. The hallmark connects the visible stamp to a purity percentage.
The stamp 417 means 10K and is very common in Canadian jewellery. The stamp 585 means 14K, the stamp 750 means 18K, the stamp 916 means 22K, and the stamp 999 means fine gold. A 375 stamp normally points to 9K imported jewellery, so it should not be priced as 10K.
Why hallmark and weight must be checked together
A hallmark alone is not the value. Weight and purity work together. Ten grams of 417 gold has much less pure gold than ten grams of 750 gold. That is why a buyer quote should show both the weight and the purity used in the calculation.
If the hallmark is damaged, missing or suspicious, do not guess on a valuable item. A proper test can prevent overvaluing plated items or undervaluing solid gold. Gold-plated and rolled-gold marks should not be priced as solid gold hallmarks.
When hallmark value is not the final selling price
The value shown here is melt value. It does not include designer value, antique value, gemstone value or coin premium. It also does not guarantee a buyer payout. Use it to understand the metal baseline, then compare buyer offers or appraisals.
For Canadian sellers, hallmark lookup is usually the step before a calculator. Once you know whether the item is 417, 585, 750, 916 or 999, you can move to the matching price page or add the item to the scrap calculator. That avoids the common mistake of pricing every piece as 24K or accepting a quote without knowing which purity the buyer used.
Marks that need extra care
Imported jewellery, older repairs and worn rings can carry marks that are hard to read. If the piece has GP, GEP, RGP, GF or plate-related wording, it should not be treated as solid hallmarked gold. If the mark is partly missing, compare it with the item colour, weight, wear pattern and a professional test before using a high melt value.
Some Canadian items also carry maker marks, assay office symbols and date letters. Those marks can be useful for identification, but the purity number is what drives the melt calculation. If the item looks antique or branded, check resale value before assuming scrap is the best route.
How to check a small or worn stamp
Use bright light, a phone macro photo or a jeweller's loupe before entering the mark. A worn 417 can be mistaken for another number, and a tiny plating mark can be missed on chains or clasps. If the stamp is unclear, treat the lookup result as a starting point and ask for testing before using the value in a sale.

What do GP, GEP, RGP or GF mean?
These marks usually refer to plated, electroplated, rolled gold or gold-filled items. They are not valued the same as solid hallmarked gold.
Should I sell hallmarked jewellery as scrap?
Use melt value as a baseline, but check for designer, antique, coin or gemstone value first. Some items are worth more than scrap.
Which hallmark matters most for a cash-for-gold quote?
The purity hallmark matters most: 417, 585, 750, 916 or 999. A buyer also checks weight, testing result and payout percentage.
What if my jewellery has letters as well as numbers?
Letters can be maker marks, date letters, manufacturer marks or plating marks. The purity number still drives the melt value, but unusual marks are worth checking with a jeweller if the item may have extra value.
