Is it possible to determine the approximate age of these bricks only by seeing their injection points? Is it possible to determine the approximate age of these bricks only by seeing their injection points?
I cannot tell by the injection markings but having been a lego collector since 1967 I can tell that they are around that era. They look like some of the original ABS plastic. I also have some even older lego bricks in my collection (circa 1960) and they are of a different plastic but you cannot see the molding points on those.
