Hi Deb -- You probably have a well-worn 8 reales coin from the old Republic of Mexico.
These coins contain 0.786 troy ounces of silver. So that sets the minimum value they can attain. For instance, if silver is selling at $12 per troy ounce (look it up for today's price at kitco.com), the minimum price is 0.786 x 12 = $9.40.
Coins with the liberty cap and starburst pattern were minted in smaller denominations than 8 reales. In fact, denominations of 1/2, 1, 2, and 4 reales look the same, only smaller. The denomination appears explicitly on the coin in the place where '8R' appears on the 8 reales. Look for '1/2R', '1R', '2R', or '4R' on your coin and, if you have one, click to this appraisal page.
These are nice coins from Monaco. They are made of copper and aluminum. Since they are modern coins made of non-precious metal, they are not worth very much. Approximately, for all denominations:
worn: less than $1 US dollar approximate catalog value
average circulated: less than $1
well preserved: $1
fully uncirculated: see below
Coins that look like our image are fully uncirculated, or nearly so. The values above apply to all denominations. Here are the variations with denomination for fully uncirculated coins:
Australia issued these coppers from 1911 to 1939. After that, kangaroos appear on the back of penny and half penny coins.
Most of the pre-39 pennies and half pennies are low in value. Below is a list of approximate catalog values for just about all the dates in the penny and half penny series. Special *better date* coins appear on this page after the common date values.
PENNIES (COMMON DATES BEFORE 1932)
worn: $1 US dollar approximate catalog value
This is an interesting series of coins from the Federal Republic of Germany. The girl planting a tree appears on all dates, but the inscription changes between 1949 and 1950, as follows:
1949 and 1950: BANK DEUTSCHER LANDER
1950 to 2001: BUNDESREPUBLIK DEUTSCHLAND
The 1950G coin is important, and we describe it first. There are two 1950G coins. One is very valuable, and the other is not, as follows:
1950G BANK DEUTSCHER LANDER
Just about all of Swiss 5, 10, and 20 rappen coins are minted in copper nickel. The one in our picture is special ~~ it is minted in brass. Copper nickel coins are lighter in color, but the pattern is the same. Some coins were also minted in aluminum brass, which takes on a golden color.
These long-running series have a few special dates, but most are worth less than $1 US dollar in average circulated condition. Here is a run-down on these three coin series. Values shown are for coins in well preserved condition, like our picture. If your coin is not a nice as the picture, it will be worth substantially less. If your coin is fully, absoluately uncirculated, then it will be worth about twice these values:
Like all British coins, the reigning monach appears on the 'heads' side. In the case of the South African farthing, Kings George V and George VI appear, then Queen Elizabeth. The back 'tails' side has the two bird pattern on all coins.
The older versions of the coins can command decent collector value, but modern coins are worth very little. Here are some approximate catalog values. Use our Important Terminology link (at the upper left) to properly interpret these values and convert them to actual buy and sell prices.
