Remember that only a very small percentage of foreign currency is actually collectible.  Here are a few signs that your foreign currency might not be worth much:

1)  It is a very high denomination - this is a sign that the note was issued during a high inflation period.

2)  The currency was brought back to United States by a serviceman who was overseas at war.

3)  The currency is from 1960 or newer

With that said, some foreign currency can be quite valuable.  Money from the 19th century has a chance to be collectible.  Money from stable European countries like England, Luxembourg, France, etc could potentially be valuable.  There are exceptions to every rule.

We purchase all collectible foreign currency.  Please send us an email and tell us what you have.
