I bury mine around on my property for someone to discover in the future. I have a 5 gallon water jug and a couple large coffee cans buried right now and have a full coffee can waiting to be buried
I'm going thru coin rolls that I purchased from thrift shops and some off eBay over the summer. I travel from Arkansas to Montana for work and I have some favorite places I stop at to look for coin rolls then in the winter while on layoff I look thru them.
