Scott #356 Paste-Up Census Update!

I've restructured the main census page to make it easier to get the details on each individual entry. There are now individual pages that show the full size images of each census entry along with images of the back sides where available. Along with the images one will find all certificates listed for the entry, the tab orientation including what, if anything, is on the tab, height of the entry, up to date auction histories for each entry as well as any additional thoughts or notes that I have gathered for the entry.

Announcement!

After many years of self-learning the art of expertizing Washington/Franklin issues, Kans./Nebr. overprints and other assorted U.S. issues I'm happy to announce that as of 2016 I've been accepted into the American Philatelic Society Expertizing (APEX) Service as a journeyman expertizer of the Washington/Franklin series of stamps. I will now be able to expand my knowledge of the expertizing arts under the tutelage and mentoring of some of the best and brightest philatelists the hobby has to offer.

How accurate are government perforations?

I've done a small study of much government perforations vary from the "ideal" measurements stated in reference books, the full storry can be found here.

I've been made aware of a website that details the early days of dodgy EBay sellers.

I urge everyone to go and look at this site, it's well worth the time to go through all of the information presented, it's a well-organized written history of a dedicated few to clean up unscrupulous stamp sellers on EBay.

Changes to my RF overprint page.

I've decided to split up my RF overprint page into three distinct pages:

The research I've done on a genuine RF Overprint cover that I own.
Fake RF overprints I own and why they are fake.
Fake RF overprint listings that I've found and keep finding on eBay. Updated.

New website to help out stamp buyers.

I get a weekly newsletter from Mr Fancy Cancel (Frank Kaplan) and in the 9/25 offering he mentions a website started by Bill Weiss and Don Denman called Stamp Smarter. In a nutshell the site has a number of contributors that scour the major stamp selling sites, and then make that information available for all to see. I was very impressed with the site and I, like Frank, encourage all who see this to go have a look.

Damaged Cover with Scott #814 and Post Office Seals.

I was asked by a client to look at a damaged cover franked with a Scott #814 that had been put back together with postal seals. It turns out the auxilary markings may be an earliest known use. Click on the image below to see to whole story.

I got a reply back from a member of the Auxiliary Marking Club on my request for information.

So you think it's a Scott #10?

Most of the stamps offered up on Ebay identified as Scott #10 are really Scott #11. So how can one tell the difference? I've written up a paper outlining a few easy things to look for that will separate the wheat from the chaff.
