I just sold an old laptop not worth more than $50 for nearly $200.
The guy knew exactly what he was bidding on, even emailed me

In a lot of cases, someone needs an item for a specific purpose. I to, sold an
ancient Notebook (an ancient Twinbook of all things) for a lot. The guy needed
it because it happened to fit perfectly into his studio panel and system (he
was a composer).
Worth 20 bucks to me...went for 175 bucks. Everyone was happy.
