The value of a commemorative gold coin depends on a variety of factors, including the design, mint date, condition and how much gold is in the coin. Coins with a high gold content are typically worth significantly more than commemorative gold coins produced of a secondary metal with gold overlay.
The value of coins made of gold depends heavily on the type of gold used, the amount of gold in the coin and the current trading value of gold. Coins with a gold overlay are typically worth less than the cost to refine the gold. Gold-plated commemorative coins have little to no financial value. Commemorative coins are created as collectible proofs and not as legal tender, so they have no value as currency despite many having an assigned denomination.
