re: What kind of perforation is it?

It is a private perforation used in coil dispensing machines, more info here https://stampsmarter.org/1847usa/PrivatePerfs.html

The ink on the back of the stamp is called 'setoff' and is explained on this page

go to Don's first link. if you scroll towards the bottom of the article, you'll see the various private perforators all listed and examples of those peforations. They are listed alphabetically, so Shermack comes near the end.

The various Shermack types are easily discernable, and Type III especially so. That is the type you posted. It is also the most commonly found of all the Shermacks. There's usually a slight premium for a stamp, and a large premium for on-cover usage.

and, Don, thanks for putting up those great links.
