Don't use metal polish to remove the spots, Meutia. That will ruin the value of your cool British coin. Be sure to handle your coin by its edges only. No fingerprints allowed!
It sounds like you have a gold sovereign from 1914. It could be a half sovereign, because the two coins look alike, only their size is different:
HALF SOVEREIGN: 19 mm diameter, 0.118 troy ounces gold
SOVEREIGN: 22 mm diameter, 0.235 troy ounces gold
Apparently it was not that long ago that Reader's Digest magazine ran a promotion and produced a bunch of replica coins that look like Austrian gold ducats. Most have a date of 1752. Some carry no date. You can see an extensive discussion of this coin on CoinTalk.
Genuine ducats are things of elegant beauty. In the comparison below, check the overall crisp appearance and intrinsic appeal of the genuine coin from Stacks Bowers to the mushy and lifeless appearance of the fake.
I like French coins. The designs are always interesting, artistic, and well done. This design is no exception.
This is a complicated series of coins. It runs from 1933 to 1952 with the same patterns on front and back, but several variations apply. Some coins are made out of nickel, others aluminum, and still others aluminum-bronze. Also, some coins have mint marks and others do not.
In general, for most coins except those noted below, here are approximate catalog values:
The 1957 5, 25, and 50 pesetas coins from Spain are ones that can get collector juices flowing. The vast majority of these coins are very common, low-value pieces. These coins are made of copper-nickel and are worth only face value. A collector might pay a few US dollars to add a fully uncirculated specimen to his or her collection.
ALL COINS EXCEPT THOSE DESCRIBED BELOW:
worn: less than $1 US dollar approximate catalog value
average circulated: less than $1
These are modern coins made out of aluminum. Some collectors might pay $1 or $2 US dollars to buy a nice specimen for their collections.
Nice coin, Mickey. These old silver rupees from India represent an interesting series of coins, and many of them -- especially the older dates -- are valuable.
The coin in our picture is one of the earlier versions. Later coins changed monarchs (India was British until 1947) and reverse designs, but the basic coin was the same all the way from 1862 to 1947. You will see coins in this series as follows:
1/4, 1/2, and 1 rupee
