Most of my computer-vended stamps are on Vario sheets. The Danish "bridges" stamps (2 different series) are in sets of 4. You have 3 of the 4 from series II. There are 2 different printer settings for these (wide and narrow) as shown on your third line down. Michel prices them the same. They were sold/vended in values from .25 Kr. to 99.75 Kroner, in increments of .25 Kroner. In my experience, the vast majority of these are 5.50 kroner stamps. Higher values (parcels, heavy letters, etc.) and make-up values are harder to find.
The Danish stamps are probably the only computer-vended, self-adhesive stamps that I would dare to soak. I always experiment with damaged ones before trying to soak "collection quality" stamps.
