Impact of gumstains on value

I read that title wrong at first glance and thought this was going to be really weird.

Yes, I am ten years old with a potty mouth, but is it all that surprising? I play with baseball cards.

How common is a gum stain on the obverse of a card? What does it look like anyway? I opened wax packs in 1952, but seem to recall that Bowman - maybe not Topps - placed a buffer in the pack to separate the gum from the cards. My memory may be off on that though. That has always caused to wonder if the very common stains on the reverse of early '50's cards is actually from something other than gum, since in all the packs presumably with no buffer, only one card would likely be touching the chewable item - the other five to six not touching. Of course, there was plenty of gum dust in the pack, the aroma of which is something that never left my data storage facility, but I don't think that dust could produce any staining. Anyone have any thoughts or evidence to bear on this conundrum?

Gum or wax they are two entirely different stains. wax doesn't bother me a ton on a card for my collection. gum stain no thank you.

Wax stains can generally be rubbed off with a cloth or panty hose, especially if they are on the front. They seem to stay on the surface of the card. And I personally have no issue with doing that.

Gum stains on the other hand, can penetrate the card's surface and cause 'bubbling' on the front. They seem to be a more permanent type of damage than the wax stains.

Probably some of the worst cards for gum stains were the 1981 Donruss and Fleer- their first issues. I can remember putting entire boxes of them in the freezer to be able to 'pop' the gum off the card. Hey, maybe there are still some boxes in there - I'd better check on that.

This one was a travesty. You win some, you lose some.

I don't think any kid opening a pack in 1955 would have encountered a "stain" of that kind. The back of that Conlon card, and maybe the next one - Ted Gray to some extent, were heavily stained, but the other seven cards appeared to be unblemished. So, the gum oil only managed to penetrate the top two cards over the course of 60-plus years. I imagine Topps was also in the practice of inserting the gum slab on the top (obverse) side of the cards, which would strongly suggest that the stains on the reverse side almost always came from wax, not gum. But, if the wax wrappers tended to stain the back of the bottom card, wouldn't that indicate that wax staining only appears on 20% or fewer of all cards from the period? It is questions of this enormity that I appeciate for taking my mind off of world events.
