Those are interesting perforation shifts. Unfortunately, in the eyes of most collectors they come under the category of "Freaks" as the minor perforation shifts really do not impact value by that much. A major perforation shift would have to occur to make them significantly more valuable.
It is difficult to apply a catalog value for such things since they are not that common and there is no way to tell how many of them may be out there. The real value is in what a buyer is willing to pay and what a seller is willing to accept for an item. They may hold some extra value to collectors of these sort of things, but since the majority of collectors would either want perfect examples or errors much more significant than shown in the above scans, the premium value is really quite modest.
The work provided at this link (advance to Sections 30 through 39) attempts to address what one might expect to obtain in premium value for such "Freaks". If this estimate is to be believed, it would seem that most are not exactly of major value, but they still represent a nice addition to a stamp collection.
