No. The 144 Classique, the small Meisterstück that runs on a cartridge or a converter, was built in very large numbers over several decades and discontinued around 2000. The end of production alone creates no scarcity: the second-hand market is amply supplied, and prices have moved at a modest level for years.
With writing instruments, increases in value arise almost entirely from rarity — from a small edition, a special version in precious metal, an unusual nib grind, or a historically significant model in good original condition. Mass-produced models such as the 144 fall into none of these categories, however well regarded they are as everyday pens.
A collection of ordinary Montblanc pens is therefore no use as an investment; anyone looking for a return is better served by the conventional forms of investment. Collecting should be done for the pleasure of the object — and on that score the 144, as a classic, certainly belongs in any Montblanc collection.
