Based on my own experience, people were still using typewriters into the 90's. Not because it was cool, but because computers were still pretty lame and not everyone had one.
usually a well kept red valentine typewriter is worth around 150-200 euro here in europe but i know in USA they have been sold for as much as 500 usd.
If it is a Valentine with the case rubbers intact and made in Barcelona with the little instructions sheets it may be worth as much as $350 US. They are quite keenly sought by collectors now although at the time of manufacture 1969 they were a very slow seller due to the radical design and colour. Olivetti made a second manufacturing run made in Mexico in the 1990's and these also failed to ignite the buyers. A machine truly before it's time... Ray Murray (ex Olivetti Manager) Adelaide SA
