What's a 30-year old Grace F9-E Ruby worth?


Since vinyl has caught on again, I brought out my turntable from the 90's and played a few vinyls. I was surprised to see that the cartridge still plays fine. To make a long story short, I not into vinyl as I once was. My interest has shifted to 24-bit music, limited as it is.

Any idea what this cartridge is worth given its age.

I sold an F9-E for $250 on Audiogon a couple of years ago; not a Ruby but standard. But it all depends on if there is a buyer who wants one when you have one to sell; prices can vary widely.
Dear Reelnai: Worth to own for any one. The Ruby IMHO was the best Grace ever and today competitive with the best LOMC cartridges.

Regards and enjo the music,

Start an auction here or on ebay and you will know. Can you estimate the extent of stylus wear?
OK. I confess. After a year of cartridge-buying abstinence, I just bought a Grace Ruby for $500. I don't know whether I overpaid or not. But, in mint condition in the original box, they don't exactly grow on trees, as my mom used to say. Once you decide what to pay, you will then have to find one. It took me about a year.
