Transformers Generation 1

Transformers Generation 1, Hasbro's 1984-1991 line rebranded from Japanese Diaclone, built a billion-dollar franchise and remains the most iconic robot toyline. The most valuable figure is a sealed Optimus Prime, selling for $2,000-$10,000 based on box condition, while pre-rub examples with the rare 'no indent' head variant can add 20% to that price. Fortress Maximus, the 22-inch flagship, commands $3,000-$8,000 boxed, which is 50% heavier than the average G1 figure's value. Even common figures like Jazz and Sideswipe fetch $200-400 mint-in-box. When compared to #6's GI Joe USS Flagg, the Transformer market boasts wider accessibility, with over 300 distinct character molds available to collectors.
