Between 1974 and 1987 France minted 10 franc coins in a copper alloy, either nickel-brass or nickel-bronze. Before 1974, 10 francs were in silver, and after 1987, 10 francs returned to collectible silver and gold coins, with a few years of nickel 10 francs as well.
The copper alloy coins make for interesting collecting. The pattern shown in our picture is the 'standard' pattern for this type of coin. But several other patterns were produced as well, all of them very pleasing and artistic. In general, the 'special' pattern coins are worth slightly more than the 'standard' pattern:
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:
These are beautiful old coins, Rachael. The fact that your coin is bent, however, will lower its price to gold bullion content alone. There will be no numismatic (coin collector) value over and above bullion value for bent coins.
Here are the statistics:
10 CORONA: 18 mm diameter, 0.098 troy ounces gold
20 CORONA: 20 mm diameter, 0.196 troy ounces gold
To find bullion value use a web site like kitco.com to find the up-to-the-minute price of gold. Then multiply that dollar amount by 0.098 for 10 coronas and 0.196 for 20 coronas. At the moment, kitco reports $1290 US dollars per troy ounce, so Rachael's coin is worth $1290 x 0.098 = $126 (Base value=BV). If you go to sell this coin to a gold dealer, he or she will charge you a commission for handling the transaction. For a single coin, a reasonable commission would be 20 to 40 percent. If you had 100 coins, the commission percentage would be lower.
Most people think that old fashioned wheat-backed Lincoln cents (pennies) are very valuable. In fact, millions and millions of them were minted and all but a handful carry no significant value. When worn or in average circulated condition, most wheaties are worth a few cents each. Even in fully uncirculated condition, coins dated after 1933 are worth a few US dollars each. For most coins before 1934, here is how the catalog values run:
LINCOLN CENTS DATED BEFORE 1934 (except as noted below):
These are some great-looking coins. Along with the 1915 S half dollar (click here to see it), four gold coins were minted at the San Francisco Mint to commemorate the Panama-Pacific International Exposition held in San Francisco in 1915.
These coins all have a base value relative to their gold content. The current base value can be determined by multiplying the AGW (actual gold weight, posted below) by the current spot price of gold. Current prices can be found on kitco.com. On top of the base value, each coin carries a premium both for their historical nature as well as their appeal to collectors.
Let's see. X in Greek is the letter 'chi' and P is the letter 'rho.' So XPON is 'chron' from which we get 'chronological -- in time sequence.' It turns out that KAAH XPONIA means Happy New Year in Greek.
This is a exceptionally poorly produced Happy New Year token made to look like a British sovereign.
It is worth a few US cents. If that.
