Are old-school Capital Plastics holders (No date, 50c) in their original packaging worth anything?

Ya know, over what a new one is worth? Just wondering before I rip these bad boys open and get into them. No dates or trademarkings on them, plus being 50c each, they gotta be old as heck.
Here's the patent # information for capital plastics holders in general, which is the closest thing I can find.

The only way to find value on something like that is to put it up on an on-line auction site. Having done that, hope that there are two enthusiastic coin holder collectors out there that see the auction and bid like crazy!
Check eBay sold listings, if there are any.
I would kind of doubt it.
It's not like it's a pack of unopened baseball cards.
everything has value the question is just how much.
The old saying supply and demand determines price!
One thing I like about Capital Plastics is that they are sort of old school - I am not sure they have changed much over the decades. The Plexiglass is very stable, but the plastic for the screws might (?) not be as durable - not sure.
All combined, not sure I would pay more for old holders which look petty much (or exactly ) like newer ones, but someone might,
The screws tend to discolor and become yellowish.
Well, they're not the 3-layer plexiglass type, they are the thinner plastic over cardboard type, right? I have a 20th century type set holder made of those matetials, purchased in 1980.
They might be worth a couple dollars each in the packaging, and a couple more dollars each if opened and coins put in.
Let them sit with BU morgans in them for a few more decades, and then have valuable "toners" in 2050 or so..

The capitol holders came in different levels.
RE the screws that do change in color can be replaced, they are can be had from a number of places!
I'm not sure that type of holder used lucite plastic. I know the screws did not and will yellow with age.
I don't like the cardboard inserts, (those are cardboard correct?).
This thread inspired me to go to toms-world (the basement) to see what I had in a box of empty holders. Here is what I found.

50c as it states on the package
