Try not to worry, just leave them alone.
But some items do sell for big money because they're collectable. eg SME 3012 arm, Audio Research SP10 and plenty of others.
@oddiofyl I have a second system because I can't bear to sell my collectable stuff. It runs Simon Yorke Zarathustra, Zeta arm, Anna cart, SP10, Krell KSA50, Audiostatic ES200s. It is installed at the opposite end of my dedicated room. My chair is in the middle and can spin around.
Around 1970 I bought an SME 3012 for £12 and put it on a turntable kit with my self built plinth. I bought a Linn about 6 years later. I kept the 3012 and then noticed they were selling for £60+. I sold it. They are now £600-800.
