As mentioned above,, "There are no dumb questions."
We are not born with any knowledge. We learn by various methods. Asking questions is just one way to learn anything. Knowledge is when you retain the information you learned. Teaching is when you share it.
Long ago,, as I started my path of Ruger fun,, guns were a focus. But I also chased the "cheaper" stuff,, like catalogs, paperwork, & odds & ends. I quickly learned that as a collector,, having a "complete package" of something enhanced it's value.
Why?
Because things like the boxes were OFTEN thrown away, and the guns were kept. Now, you have a shortage of boxes,, when compared to the number of guns. Throw in the often shorter production items,, such as the Single-Six Lightweights,,, the scarcity of boxes rises. Next,, when there are variations of things,, like the same boxes,, where it can have either a "green wreath, or a black wreath" making one more scarce than the other,, values rise.
And to post a slight correction,, the black wreath LWAC box shown is not the holy grail of boxes. There are other boxes worth more,, and in just the LWAC boxes,, a green wreath is worth more than the black wreath ones.
Then there are the rarer OM FT boxes for the 10" guns. Especially the .357 10 FT.
But basically the OP's question is easy to answer. Collectors who want a rare, hard to find item, will pay more for it, than many might understand.
Just ask Miss Penny,, she thinks paying for boxes isn't "intelligent." But she also understands that people WILL pay,, and as such,, knows NOT to discard ANY boxes I have.
