You have a a 20 centavos coin from Chile, Joequimby. It is minted with 0.144 troy ounces of pure silver. At over $10 US dollars per ounce, that's more than $1.44 in silver content alone. Look up the current value of silver at kitco.com and you can easily compute the *basic value* (BV) of the coin from silver content alone.
The 50 centavos looks the same, only bigger. The 50 centavos contains 0.362 troy ounces of silver.
These coins are hard to find in well preserved condition, and even tougher in fully uncirculated condition. The catalogs value provided below reflect this fact. The tables below give approximate catalog values in US dollars.
worn: $5 US dollars approximate catalog value
average circulated (like our picture): $15
well preserved: $30
fully uncirculated: $200
coins dated 1852 are uncommon, multiply the above values by 2
coins dated 1859 are rare, multiply the above values by 10
Coins dated 1859 with the 9-over-8 overdate variety are scarce, multiply the above values by 3
An overdate means that, under magnification, the number 8 should be visible under the number 9 in the 1859 date. If this number is not visible, the value goes up. It is important to note that on worn coins, the underlying number can be almost worn away. When in doubt, assume that your coin is of lesser scarcity.
worn: $10 US dollars approximate catalog value
average circulated (like our picture): $20
well preserved: $100
fully uncirculated: $400
Some dates are worth more:
Coins dated 1856 that are NOT of the 6-over-5 overdate variety catalog at values twice those listed above.
Coins dated 1858 are slightly uncommon, multiply the above values by 2 for worn and average circulated coins, and add $20 for well preserved coins.
Coins dated 1860 are very rare, and catalog at $250 when worn, $650 when well preserved.
Coins dated 1862 are scarce, multiply the above values by 2.
Coins dated 1862 with the 62-over-52 overdate are even scarcer, and they catalog at $25 when worn, and $185 when well preserved.
NEVER CLEAN A COIN. CLEANING RUINS VALUE.
These are all catalog values. Remember that actual buy and sell values will be less than the catalog values shown, as explained in detail on our Terminology page.
