I was watching some youtube videos on people digging up a cache after 1 year or two and some of the stuff was dry and looked like it did when they buried it while others were soaked, oxidized and basically ruined.
What I am wondering is one of them had silver in it and someone said plastic bags will "ruin" silver, why so?
Also I have noticed that some .45acp ammo I put in plastic bags looked oxidized after a while even though they were not buried and just ziplock bags.
All of them seal"a"mealed the bags by the way but some lost the vaccum being underground for a while.
