Number one on your list should be food.(then the other stuff on your list.)
That's the first thing you'll need when you wake up one morning and discover that the world has changed forever and there's already no food in the grocery stores.
Get some junk silver and maybe a little gold.
I have nickels too...they're 75% copper and 25% nickel.
LOL, my grandfather owned a restaurant and was an avid coin collector. I couldn’t count the numbers of nickels and old pennies under the house. 100,000+.
