Well I got lost again..found another and lets see if I am right..Scotts 578 Rotary Imperf
How did I do?? man tough to be sure on any of these but dont you go where it says Imperf and that should be it,,but just above that its says for listings of other perforated stamps of designs a154-a176 see...then they talk perfs 11 x10 perf 10 perf 11 and then perf 11 x 10 1/2...this is where I get lost ..have to get that perf reader soon I think..do I have a great card here or another dam common,,and are stamps like this worth more on say a post card ect..rather than off something?
Thank you all!

Perf 10 Scott 597. Rhe color (dark yellow green) is wrong for the coil waste which is always drak green.

Editted for brain freeze

no perfs on bottom or top russ,,isnt this imperf?

Imperforate means no perforations at all on all four sides. This is a coil, named because they were coiled in a roll and usually sold in a stamp vending machine.

Imperforates look like this.
