Black Widow, vol. 8 #1G upc should end with 171 (as can be seen in the image of the back cover).
Black Widow, vol. 8 #1H does not exist. For reasons I can no longer remember it didn’t come out until vol. 9 where it is #1E. Oddly, the cover images for #1H and #1E are reversed. This is the correct image for vol. 9 #1E
