ID Please: Maybe 634?

I'm trying to school myself so I am at least conversant in the realm of Washington/Franklins. I've a long way to go!
I think I may have this one right. I gauge it at 11x10 1/2. Could it be Sc. #634. It's in rough shape, but I am going to try on my own to ID as many as I have (dozens).
Thanks,
Stephen

Technically, this stamp is not a Washington/Franklin. The WFs consist of stamps with only the portraits of Washington or Franklin. This stamp is from the regular series of 1922-26 which, while it does have a Franklin & a Washington, has the portraits of many other individuals along with several non-human subjects in the higher denominations. I also agree with your ID.

I'm glad I asked. Thank you JL, duly noted.

Could it be the "long ear" type?

It is hard to tell from the picture but also check for possible thick hair lines and a gap in the scroll. It is possible that it is a 634A.

Alas, zero chance that it is a 634A.

Thanks revcollector!

I was struggling with the picture (I thought I saw a gap between the scroll and frameline but the hairs...(can't tell very well with that image).

It's funny, because I thought I saw the thicker hairs but dismissed it. However, I do see a gap at the scroll. The ear is tough to tell.

Re: sub varieties:

For the "long ear", I would not get too bogged down in this level of minutia. Although it will be "bad math" because each plate was not used for the same number of impressions, there were 483 flate plates of 400 stamps, and 28 "electric eye" plate of 400 stamps for Scott 634. This means the long ear variety (one position on plate 20342) has odds of 1 in 204,400 plate positions. Having a small accumulation will be extremely long odds.

For 634A, there were 6 plates made versus the 511 total plates of Scott 634, thus a ratio of slightly better than 1 in 100, again assuming badly that all plates were used for the same number of impressions, but it gives you an idea of the broad odds. 634A is quite findable.

Learn the basics first. Assume you have the most common variety, unless you can directly rule it out by some feature.

And yes, the definitive series of c1908-1922 featuring only Washington & Franklin is what collectors call the "Washington/Franklin Series". The 1922-1938 definitives are most often called the "Fourth Bureau Issue", and are a good place to get an understanding of flat versus rotary printings, and perforation differences, before adding the complexity of watermarks and offset printings found in the W/F series. It is a good 2-step learning process.

Thank you John. It is tough to know where to start. Thanks everyone for your thoughts and input.
