wtf

I do not know what is going on here or what it has been through but this was a few rocks up and it had weird cuts and carvings , is obviously old and I think where I found it is where kids go hide to chug the beers they stole from the cooler.

Found these buried deep in the ground! I wish I could see what the heck they are ... the silver one is very heavy and isn't magnetic, could it be something ? I included my steel penny because I Also found it in my yard and it was so shiny 😲
