50 euro bills are offered on eBay for up to 700 euros. But what makes the banknote so valuable that it is offered for 14 times its value?
The seller states that the star on the back protrudes far into the serial number and is not completely printed.
Other providers also sell 50 euro bills for many times their actual value. Often, notes are offered with printing errors or special features.
It is true that many 20 and 50 euro bills are in great demand with collectors – if they have a special feature. Namely a rare serial number.
For example, if the serial number consists of many identical, consecutive numbers or if the consecutive numbers are repeated rhythmically.
A so-called palindrome in the serial number also increases the chance of holding a valuable banknote in your hands. A palindrome exists when the number can be read equally from the front and back. For example: 23499432.
