I've dealt with some odd ephemera before... Honestly, I think a hundred bucks would be a generous replacement value for insurance purposes. You might be able to get away with a higher valuation if it's bundled on a policy with other stuff. three hundred would be pushing it, especially if it's not mounted and framed.
The patents that go for a lot of money are usually bundled together with the relevant engineering drawings and other documentation regarding the development of the patentable idea (laboratory logs, pictures of prototypes, etc. For a patent to be worth much just by itself it would have to be something really momentous, like Graham Bell's or Marconi's telephony patents, one of Bessemer's patents, etc. OR it would have to have the name of a MAJOR celebrity attached to it (Think Frank Sinatra major).
It's very interesting to me that this is dated 1965. I guess it must have something to do with the V4? It seems rather early to be connected to the SVT, but kind of late for the B15. Maybe it's for the mystery pickup! Now, if it was and you also had some engineering drawings for it, that would be super cool, and worth a little more. But by itself, it's just a beautifully printed receipt. Still worth putting in a nice frame, though. A serigraph always has a certain romance that offset printing never will. Not worth much, but still cool.
Edit: The most valuble patents are the ones issued before 1800, some of which have Thomas Jefferson's signature.
