Guernsey Overprints

This list has been prepared in an effort to protect collectors from a few unscrupulous dealers who are selling faked overprints.  The list has been posted worldwide on our and various other websites, including the International Bank Note Society's (London branch).  We hope this thwarts the potential influx of fake overprints.  If the prefix / serial is not listed here there is a very high chance it is a fake.  Happy Collecting Pam.

 If after looking at the listing you find you have an overprinted banknote where the prefix/serial is not listed, send a scan at 200dpi as a jpeg and we will add it to the listing.

The list below are the known sellers of fake overprints of all countries and types on ebay.  Collated by Colonel Joe Boling and listed online on the IBNS Forum

Some of the above have two or more names and have changed their online names over a period of time.
