Suspect it won't go for much as it's not in Freeman, Gouby's book probably has not had a high enough circulation for the variety to be well known 20th century penny varieties don't ever seem to get listed as such on Ebay (except 1902 LT and 1926 ME) , how often are die varieties of 1905, 1908, 1913, 1915, 1916, 1921, 1937 listed let alone 1940 or 1944? 1903 - open 3, and 1911 Gouby X are both relatively unknown, so you just need to look carefully at sellers' photos, I'm still keeping a watch on 1908, 1909, 1913, & 1922! anyone got a 1967 "tidal wave" ?
