Is a Staedtler Mars Slide Rule worth any money?
A family member of mine left me a slide rule and i have no use for it so i planned to sell it. I look on a website that said a Staedtler Mars slide rule model number 544 28 made in germany is extremely rare and worth a lot of money. I was wondering if this is true
IMHO think as a novelty item you might fetch some money for it. I haven an old engineering grade slide rule at home that I've never tried to sell it. Your best bet is to contact and antiques dealer and maybe they can give you some good advice.
