Ok. I though I remember there was a posting ct that said there is a 1935 G note. “Only one” that was missing “IN GOD WE TRUST”. I was going though my notes and I have several 35 notes that have that missing... was it the whole run of the note of 1935? I know one of them are really rough. That is one note I got when I first started to collect them and the other one has some staining but crisp... Thanks guys!!
The treasury website has the following information regarding IGWT on the dollar bills: One-dollar silver certificates series 1935, 1935-A, 1935-B, 1935-C, 1935-D, 1935-E, 1935-F, 1935-G, and 1935-H were all printed on the older flat-bed presses by the wet intaglio process. P.L. 84-140 recognized that an enormous expense would be associated with immediately replacing the costly printing plates. The law allowed BEP to gradually convert to the inclusion of IN GOD WE TRUST on the currency. Accordingly, the motto is not found on series 1935-E and 1935-F one-dollar notes. By September 1961, IN GOD WE TRUST had been added to the back design of the Series 1935-G notes. Some early printings of this series do not bear the motto. IN GOD WE TRUST appears on all series 1935-H one-dollar silver certificates. https://www.treasury.gov/about/education/Pages/in-god-we-trust.aspx
