I try to go days without a question but I have so many. I have these block of used Stamps I'm mostly confident are 634 to start, as they are 11 X 10.5~then believe are Type 2. Type 2, with pics showing the bold double hairstrands. Dilemma : the color, they are darker than my other plain block of 634. So, are 634s in variable colors or is my stamps just a whole different type? I could not find a really good answer.

The pics will have my other block od 634 which is the lighter in color for comarison.
