Q&A: How much do you think a 20 peso Gold Coin of 15 Grams pure gold will cost in 10 years?

The denomination (pesos) is of no importance. The weight of the gold is. 15 grams is slightly less than a half Troy ounce, meaning the coin has a current approximate bullion value of $425. No one has a crystal ball that will say what gold will be worth ten years from now. My guess is won’t be worth substantially more than it is today.

More important is the numismatic value of the coin, which is determined by factors such as date, mintage and condition. A rare coin in a high state of preservation can be worth many times the value of the gold alone, and rare coin values, like values of other rare collector items such as art and antique cars, tend to go up over time, not down, and are unaffected by either economic slumps or fluctuating precious metal prices.

Without knowing what specific coin you are talking about, I’m going to assume that it’s a common, bullion-type coin, and it will always only be worth what the metal itself is.
