RW57b, 1990 BLACK-BELLIED WHISTLING DUCK, ERROR, BACK INSCRIPTION PRINTED ON THE STAMP PAPER RATHER THAN THE GUM, SUPERB 98, RARE, especially in this "lofty" grade of 98! It is listed in Scott & catalogued, but not priced. Some philatelic researchers have questioned the existence of No. RW57b as a genuine error. There appears to be evidence that the inscriptions printed on the gum on the back can leach through to the paper on one of the types of gums used on these stamps. Further research is ongoing. The clarity of the lettering makes us think this is a misguided theory. Before being delisted, the Scott Catalogue value of the error was approximately $3,500, 2010 PSE graded certificate, SMQ Cat($3500) (Image)
