Yes, a 1925 version exists (in both softbound and special hardbound) and does contain 18 leaves with illustrations. George Frederick Kolbe - Ford Library Part 1, Lot 524 has additional information.
The New Jersey title queried by Ray Williams is listed as #462 in my book American Numismatic Literature, and the front cover of the very rare hardbound edition was illustrated in the Champa sale - lot 1260."
Ray Williams and Roger Siboni visited my house in 2006 and I showed them my copy of the 1925 Guttag edition and commended the line drawings. I guess he/they forgot.
At the time Ray was more interested in the photographic plate to Maris over that of the line drawings published by Guttag; and he and Roger published an article about it.
I have not seen the 1927 issue and do not know if it is a reprint or an edition. The issue of 1925 has a light/medium brown and gray patina leatherette grained card stock cover with an early Art Deco floral and open book border in black ink.
Centered on the cover is the Guttag Bros. logo embossed in cadmium orange with the raised letters in the light/medium brown of the faux leather. The printing is interleaved very similar to the Cogan, June 29, 1865 coin auction catalog, with the text printed on the versos with the rectos blank. Only the fourth leaf is opistrographic, i.e., printed on both sides. Pagination skips blank leaves and is inclusive of all printed sides totaling 20 printed pages.
Julius Guttag added four new varieties to Dr. Edward Maris' list, keeping the Maris numbering system. These additions are on the last page, i.e. 20; Nos. 80ff, 81gg, 82hh, 83ii. There is a copy of New Jersey Cents published in 1925 by the Guttag Brothers in Rutgers Alexander Library in New Brunswick.
Richard Giles also located a listing for the book at the New Jersey State Library.
Thanks for the information, everyone. Now who can say "opistrographic" five times fast?
