I have a Bernina 900 (1983 purchased) and am trying to sell it I would like to know how much it is worth and how I can try an sell it.

Hi! If you want, stop by my store and bring the machine with you. I'll take a look at the condition and let you know what to do. If you are replacing we do take trade ins as well. Thanks for reaching out! Kramer's

Check other sales locations and then contact a dealer to see what they would give you for it.
