I have several old paper currency from 1910-1944. Germany, France, Luxembourg, Yen, Military currency Deutschland. How do I find out how much they are worth? Also, how do I go about selling them?

Sincerely,

You could try a place like this Old Currency | Old Paper Money | Value of Old Paper Money | Sell Old Money | Old U.S. Paper Money | Paper Money Values | We Buy Old Currency but it won't be the best price. Local coin shops would be a place to start. Have the money appraised and then ask them what they would give you for each bill.

Look on Ebay.
