Washington / Franklin - Maybe Others - Stamps From 50s Collection.

Hi everybody,

I'm from Italy and reorganizing an (old) collection.

I'm not a pro collector, just amateur-occasional.

Some stamps are easy to identify, others not.

E.g.







Washington, 1c, inperforated side with a tiny green line on it.

10x10, 22 x 18,5

I checked https://www.theswedishtiger.com/ID.html but could not identify the Scott code.

Thank you.

This is a Scott #424 or #462. If it has a single line watermark, #424. If no watermark #462. The straight edge is from the edge of the sheet where a pane of 400 stamps is cut into four 100 stamp sheets.

Hope this helps.

The stamp is from the 1914-1916 printings. 1914 if #424, 1916 if #462.

Thank you for the quick answer...no watermark so I'll put 462 next to the stamp pocket.

Another issue I'm facing is to measure this Benjamin Franklin 1c.


Is it an 11 or

11-1/4?

And 10-3/4 or

10-1/2?





It is a 22,5 x 19,25, with an M (I look the web and found that it was an anti-theft mark).

This is a perfin stamp from:
Senate, State of Montana, Helena, MT
Usually these stamps turn out to be Scott 632 (while owners think of 597 and 599)

Wow, thank you...so that "M" stands for "Montana"?
Or it is because the cancellation reads "MONT."
And where do you read "Senate".
Very interesting.

597 turns out to be 2 sides imperforated, while 599 is red. I think is a 632.

Can't get why it seems both 10-1/2 and -3/4.

There are perfin catalogs that describe the patterns used by different organizations. You can find some of them at www.perfins.org where you can also find an entire cover with this design used by the Montana Senate.

Thank you very much.

I still can't get why it reads both 10-1/2 and 10-3/4 (long edge) and 11-1/2 and 11 (short edge) on the perf gauge.

Are there any 11-1/2 x 10-3/4 632?

Most listings in the Scott catalog round the perforation rates to the nearest 0.5 None of these stamps are exactly 11 or 10.5, but only close.

For your stamp, note the details at the link here for Perf 11-70 and Perf 10 1/2-75 on the Kiusalas U.S. Specialty Gauge.

To really show the rounding done by Scott, note there are three different actual rates which Scott reports as "perf 10" (10-79, 10-80, and 10-81).
Also, make sure your perforation gauge is accurate. Have you measured it against other standards? Some are not truly accurate when made and some plastics tend to shrink over time.
Often the best gauge is to use another stamp of known rate.For example, Scott 803, the 1/2 cent Benjamin Franklin issue, is also listed as 11x10.5 and will match your Scott 632.

Thanks again.

I'll check my gauge using known stamps.

May I use the gauge on page two, printed as is, or do I need to buy one?

carlo, if you are referring to the Kiusalas gauge, then the answer is no.

Use this, following the instructions to make sure it prints at the proper scale:

Thank you very much.
