Hi, all! I'm sorry I didn't provide enough info! No, I didn't steal any coins from my grandmother

LOL thank you for all the kind replies and I understand the concern! You guys seem to be a helpful community; I'm glad this peaked my interest. No, I asked before checking them all out. Is there any terms for the discoloration? I kind of love the weird colors, and I'm keeping some of them regardless. I live with my grandmother and she understands I'm low on funds, and there's so many that she said I could take them all in.
I'll update y'all if there's any of value before I do that ! Thanks again
