USA Harding 2 Cent Perforation 11 Rotary/Flat Measurement

Interesting read. However, I genuinely believe that I do have two US 2c Hardings perforation 11 x 11. One stamp (height of outer frame) is taller than the other and based on the fact that they are both perforated 11 x 11 I think I have one Rotary coil and one Rotary from a sheet. The etching (rectangular boxes) across the face of one stamp is sharper than the other. If I can workout how to transfer from a scan to this page I will copy them for opinions, but it might have to wait for one of the kids to show me how to do it, because at 74 years of age I'm still learning how to use the PC! The stamps came from a retired RAF man, turned Postmaster, who built a fair collection one way or another, which I then inherited and now retired I can spend more time on them. Any suggestions re who to take them to for Certification would be appreciated, preferably in the UK.

I recommend that you do some more reading on the subject before sending these off.

23272949....coil??? no such stamp exists.
I suggest you take alub advice.

I had a "moment" on Saturday afternoon where I thought I had found not one, but two 11x11 rotaries.

In this case my confirmation bias swung the other way in that I was sure I was doing something wrong. Overcoming my senior moment, I decided to scroll up further on the page to see the flat plate listing. I do have to admit, it took me nearly 15 minutes to figure that little error in my judgement out.

With that I decided it was time to taker a break from sorting and have a tall Diet Pepsi.

Hope springs eternal.

If folks would search on '613' in this forum, they would find over 50 threads were people thought they had a #613. When the community told them the facts, that there are only 45 known examples of a #613 and the odds of stumbling across one is about the same as seeing Loch Ness monster, many of the original posters pushed back. Some of the posters accused the community of 'just being jealous because you do not have one'. Others told the community that we were all clueless. We typically tell folks to go spend money on a certification and then come back and let us know. To date not a single person had a #613, in the last 8 years not a single person has come back into the forum and admitted they were wrong.

Always sad to see the snarky push back from folks who did not like what they were told, for free, from experts on this forum. Doubly sad when so much information is available on stampsmarter.com and other sites. Sigh.

A flat plate perf 11 Scott 610 on the left and a rotary press perf 10 Scott 612 on the right. A rotary press perf 11 Scott 613 design would be the same height and appearance as the Scott 612. Note the ink wash darkening the unprinted areas on the rotary press 612. Comparing color, printing quality and height or width with a reference stamp with known characteristics is an efficient way to identify rotary press printings.

cfrphoto.... exactly. When I snapped to my senses, that's what I did.

OP:


According to sheetguy:



Pretty sure sheetguy means the Harding rotary coil doesn't exist. There are certainly other rotary coil stamps.
