Errors on souvenir cards seem less common than those found on stamps or currency, probably because they are produced in much smaller quantities. However, errors do exist and continue to be spotted by sharp-eyed collectors. A small sample of varieties are shown in this gallery; many other types have been reported in issues of the Souvenir Card Journal and the 1989 SCCS Catalog. Thanks to Ken Barr, John Shue, Greg Alexander and others for sharing examples from their collections. If you own an error card, we encourage you to submit scans for inclusion here.
