Your coin is worth face value, Barbara. A collector might pay a couple US dollars to add a fully uncirculated example to his or her collection. The picture shows a proof coin from Singapore. These are minted especially for collectors and never see regular circulation. It turns out the proof Singapore 20 cents is made of 92.5% pure silver (sterling silver) and therefore gets value from its bullion content, about $3.60 for silver at around $23 per troy ounce.

Yo, Bro --
You have a US large cent. These big and bold coins are also known as 'coronet head cents', and they come from a time when a cent was *worth* something!
Your 1834 specimen catalogs for $20 US dollars in well worn condition. If you look at the coin in my picture, it is in well preserved condition, so its catalog value would be about $200. Do you get the picture? Condition means a lot when it comes to large cents. The less wear, the better the value.
These modern pennys are nice coins, but worth very little. Not much more than face value. The one in the picture has good eye appeal, so a collector might pay $3 or $4 US dollars for it. With less appeal, $1 will do it for most dates. Coins dated 1950 and 1951 are somewhat rare, with catalog values pushed up toward $10 in average circulated condition.
French Solmaliland is a small territory of France located in Africa east of Ethiopia at the Bab el Mandeb Strait across from Yemen. These coins were minted in aluminum between 1948 and 1965 with French Marianne on the front and a cool antelope pattern on the back. All dates are low-value, but the earlier dates command good prices when fully uncirculated. Here are some typical catalog values based on auction results (some catalogs over-value these coins):
1 FRANC DATED BEFORE 1950:
Hi Erin -- Well that's a pretty cool coin. The double headed eagle on one side of your coin is often seen on Austrian and Russian pieces and, according to Wikipedia, has been used in artwork for millenia to represent the union of church and state -- exactly what the US Constitution forbids.
The 25 and 50 pennia Finnish coins have the same pattern and slightly different sizes, as follows:
25 pennia, 16 mm diameter, 0.031 troy ounces silver
50 pennia, 19 mm diameter, 0.062 troy ounces silver
Hi Glens13 -- From 1947 to 1960 South Africa minted large, 38 mm diameter, 5 shilling crowns in 50 percent and 80 percent (0.500 and 0.800 pure) silver. The reigning British monarch, in this case George or Elizabeth, appear on the front of the coin, and a nice pattern appears on the back. In 1952, the back shows an old sailing vessel. Other years have antelope, shields, and buildings, as shown in our secondary pictures.
Since these are modern coins, they do not command high collector premiums over their basic silver value. The coins in our pictures are especially nice, so they might fetch $5 US dollars over the base silver value, but probably not more. One date, the 1959 coin with Queen Elizabeth and an antelope, carries higher collector premiums than most. It catalogs for $200 in fully uncirculated condition.
Your coin is made of aluminum bronze, la Tomo, and I am assuming it is a reichspfennig, not a rentenpfennig. Both coins look the same and both were minted in 1924.
Between the World Wars the Weimar Republic of Germany issued several pfennig and mark coins that are sought by collectors today. They are made from aluminum-bronze, and have the gloomy 'DEUTSCHES REICH' on the obverse, with six stalks of grain forming a cool triangle above the date on the reverse.
If you enjoy animals, then modern coinage from Paupa New Guinea is for you. Starting in 1975 and continuing for a few years after, Paupa New Guinea issued beautiful coins with really neat pictures of really neat animals. Wouldn't it be fun to assemble a collection of these?
Some of these coins are issued in silver, making them valuable. Most are issued in non-precious metal. The coins in our picture are 'proof' coins. Proofs are made with extra detail and never enter circulation, so they are especially beautiful.
