Yes, I think so, but I don’t remember exactly.
There were some caches that were intentionally short-term, and that we did go retrieve. Often they were not so much buried in the dirt, but hidden, like in thick bushes, trees, or other places that people rarely look.
I had a friend who had been made a bit crazy by his parents’ attempts to restrict his sweet food consumption, which drove him to make caches of candy and food outside their house. At one point he started making a larger food cache in the forest, but it was quickly found and gleefully plundered by squirrels.
We also found some other people’s caches. Once, a memorable cache of shotgun shells.
I also have a metal chest which at one point I was going to use for that purpose, but kept, instead.
We put messages in bottles and put them out to sea. I found one recently that I never put out to sea.
I prefer mysterious messages and other mysteries, to treasures. I’ve continued to distribute those from time to time, peaking in my late teens and early twenties, and not so much any more, but I have a fair-sized trove of mysterious stuff from earlier, that I haven’t distributed yet. I haven’t thought of a particularly good place to put it, and there’s more $&#@ security cameras and paranoid attitudes and so on now, than there were before.
