Yes, they are from coils. Here's a snip from a USPS Stamps Etc. catalog from 1994 where they are listed under coils. (Current and past USPS sales catalogs are available for download from
https://stampsmarter.org/learning/P...licCats.html )
Although only strips of 17 are listed, entire coils were later made available.
There's a now defunct catalog of early US self-adhesive stamps that lists the coil size for these three as 5015 stamps. The backing paper was usually rouletted every 17 stamps to facilitate separating into the strips that were offered.
There is some doubt as to whether these coils were ever used to produce first day covers. I can't quote a source for this but recall it being discussed at the time the stamps were current.
In addition to these three stamps, there were others that were issued as coils in conjunction with convertible booklets of the same design. Beginning with the Pine Cone issue, the coils had plate numbers.
