I'm confused. I have the 1935 G Silver Certificate below, with a motto on the back. In the US Paper Money Red Book 6th edition, on pages 43 - 44, all 1935-Gs are listed as "no motto," but it has two separate entries for these. Bills listed "motto" only start with the 1935-Hs. The first 1935-G, or F-1616, lists a printing of 194,600,000. The second one, or F-1617, lists a printing of 31,320,000. I see no other differences between these entries, so I'm wondering if there is possibly a misprint and F-1617 should actually say "motto" instead of "no motto?" So is the bill below actually an F-1617? The same page has a picture of a dollar's back with no motto, but its caption reads "Back of F-1617 to F-1621 with IN GOD WE TRUST." So perhaps the picture is also wrong? It's a very confusing page for someone possessing a 1935 G with motto.
Your note is an Fr.1617. The motto In God We Trust was added towards the end of the 1935G series. Most 1935G $1 SCs did not have the motto. Late in the run the motto was added. Fr.1616 are 1935G early No-Motto notes and Fr.1617 are later 1935G notes with the motto. When I started collecting paper money, I bought a Red Book. I used it for about a month before I ditched it for the SGSS, which is much more detailed.
These are the details about the series 1935G $1 Silver Certificate in the Standard Guide to Small-Size US Paper Money. Hope this helps.
Thank you @SteveInTampa . So it looks like the Red book that I have (6th edition, dated 2020, which I just purchased within the past two months) must have an error or a typo in it, which is what I suspected, but wanted to confirm. F-1617 should be under "motto" and not under "no motto." Also, the picture on top of page 44 should show a back with a motto, not one without. The good news is that the bill above has a much lower printing number with a motto, which is one reason I wanted to confirm this. This was probably the best bill in a pile of old bills that came down to me from a deceased relative.
