I have just finished sorting my large queens and have found many interesting stamps. I have checked Flyspecker.com and re-entries.com. Some are shown on these great sites.
All of these stamps have faults/damage ranging from minor to downright ugly. But will hopefully be of interest to the variety hunters like myself. Some have been shown here on other posts.
Positive comments are welcomed, lets keep it civilised. I am too old, and have too many stamps, to learn the ins and outs and technical details of all the different papers and printing processes. I just know what I see. If you find that offensive, then please dont join in the conversation. I will make no apology for not having, or wanting your level of knowledge. Hopefully you will share your expertise, but if not thats up to you.
Catalogue numbers are by 2016 Unitrade. All are perf 12-66 unless mentioned. I have used a Kiusalas guage. All numbered flaws and varieties are taken from A large queens report by Hans Reiche.
