REF reference model 3

Hi everyone! this is my first post so go easy haha.
Basically, I have some old, very nice speakers to sell, and finding a price to sell is turning out to be a slight challenge for me. They are KEF reference model 3 speakers, I believe from the 1990s, and they are in nearly perfect condition. I listed them at 1800 (unsure) and someone who is at least trying to seem very knowledgeable about KEF said $800 was fair for this pair. I would really appreciate some knowledgeable people telling me what they're worth if possible. thanks.
