Think that auction gone a bit crazy. I've just paid £65 for very clean set from a member on here and about £60 for one NOS one recently, I'll PM you as interested if your selling. Earlier tyres do/can go for more, paid £120 for set of NOS UG ground controls but they are super rare. All IMO this of course.
