Other methods would be:
1. If you have a back yard, dig a large hole, put all coins in water proof boxes and bury them.
2. Find a neighbor that doesn't look like someone about to leave town and ask them to hold everything for you.
3. Place on front porch and cover with all kinds of Christmas decorations.
4. Give to Salvation Army and forget about all of them.
5. Leave all of them right out in the open on a table. No crooks would think of them there.
