Vintage GI Joe figures from the 1960s fetch quiet a high price on Ebay these days. However, there is something to consider. From about 1994-2007, Hasbro re-released many classic and favorite GI Joe figures from the 1960s using the same vintage designs, uniforms and equipment.
Yes, they are not worth anything since they are reproductions, but if one wants to recapture childhood, they are highly recommended.
They are part of Hasbro's "GI Joe Timeless Collection," and cover all branches of the military. US Navy Combat Diver, USAF Scramble Pilot, NASA Astronaut, US Infantry Soldier, US Green Beret, US Marine, etc...
Here are a few images:
Those are the ones I recall seeing available - Amazing. Would be worth the memories alone, don’t need vintage for vintage’s sake.
As I look at Amazon, the prices for these are creeping skyward as well.
