Most foreign coins can be grouped into four general groups; Gold, Silver, Ancient, & foreign base metal coins.
We buy foreign gold coins
The most commonly traded foreign gold coins include the British Sovereign, the Swiss 20 Franc, the French 20 Franc and the Italian 20 Lire. Because there are so many gold foreign coins in existence, we have books, websites and guides that we use to figure the price. Most of the time foreign gold trades near the spot price of gold, which is fairly expensive. Certain foreign gold coins are very rare and desirable; we buy them for a higher price.
We buy foreign silver coins
For 1000’s of years until the 1960’s it was pretty normal for nations to have silver coinage. The technical “coin silver” alloy is .900 silver, or 90% silver and 10% copper, but different types and alloys exist. Most of the time foreign silver goes around the spot price of silver. Mostly because they are not that uncommon. Certain foreign silver coins are very rare and desirable; we buy them for a higher price.
We buy foreign base metal coins
We pay $3/lb for foreign base metal coins. Most people have some foreign base metal (not silver or gold) coins laying around. A large amount foreign base metal coins that people save have been demonetized. US banks do not accept coins for exchange value.
We buy Ancient & Medieval Coins
The ancient world actually made a lot of coins. They could be made of silver, bronze, gold or copper. We have numismatic books that have tens of thousands of coins ranging from Roman, Byzantine, Greek, Medieval, Asian and more cataloged. Age in itself does not always determine the market value. Condition and demand are usually what dictates price. Some can be very expensive, especially old Chinese coins.
