In 1998, the FIBA World Championships of basketball took place in Athens, Greece. One of the ways Greece celebrated the event was by creating a commemorative coin with a denomination of 100 drachmes.
It is made of aluminum-bronze and weighs ten grams. The diameter is 29.5 mm. The obverse shows the trophy cup inside a basketball with the denomination below. On the reverse are four players in action under the basket. This is a cool coin but not valuable by any means. Here are the approximate catalog values for this coin:
Charles IV (1316 to 1378), originally named Wenceslaus, was the second King of Bohemia from the House of Luxembourg, and the first King of Bohemia also to become Holy Roman Emperor. This gold coin from his reign is very valuable. The inscriptions read KAROLVS DEI GRACIA and ROMANORVM ET BOEMIE REX.
worn: $3500 US dollars approximate catalog value
average circulated: $6000
well preserved: $12000
However, because it is so valuable, replicas and counterfeits abound.
The beaver on the back stays the same, but King George is replaced by Queen Elizabeth in 1953. These coins are worth essentially face value. If you go back prior to 1955 they start to pick up collector value when fully uncirculated. Here are some typical catalog values:
1937 to 1947:
average circulated: 25 cents (US)
well preserved: $1 US dollar
fully uncirculated: $10 approximate catalog value
1948 to 1958:
These 1 peso coins are made of copper-nickel, so they are worth very little when in circulated condition, much less than $1 US dollar per coin.
Coins that are in fully, absolutely uncirculated condition are sought by collectors. Some collectors will usually pay a few US dollars for such a specimen.
Now there is also a subtle variation that adds value to this coin. This is the kind of stuff that gets collector juices flowing.
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 small island of Mauritius, 500 miles out to sea from the large island of Madagascar, off the southeastern coast of Africa, received its independence from the British Commonwealth in 1968. From 1877 to 1978, Mauritius issued coins with the reigning British monarch on one side, and the denomiation on the other side. The 1, 2, and 5 cent denominations are made of bronze. Other denominations such as 10, and 20 cents look similar, but are made of silver and copper-nickel. We address the bronze coins here.
For more than 100 years, people have been throwing trinkets and novelties into the crowds attending Mardi Gras celebrations in New Orleans, Louisiana. Around 50 years ago, designers came up with an interesting souvenir that was lightweight and could be inscribed with the theme and logo of each particular carnival group (also known as a 'krewe').
These tokens - also known as 'doubloons' - quickly became popular among collectors and the Mardi Gras crowds (the crowds especially like them because they are made of plastic, aluminum or other lightweight metal and don't cause injury when they're being thrown from a parade float).
This silver medal commemorates the 80th birthday of Princess Marie of Saxe-Altenburg, wife of George V, king of Hanover. The superb example in our picture comes from Westfalische Auktions gesellschaft fur Münzen und Medaillen oHG, where it sold for 320 euros (about $360 US dollars) during a 2015 auction. Approximate catalog values are:
