I've carried a pound note in my wallet for the last 30 years - but that's a superstition kind of thing. I like the carrying silver idea, but a half-ounce might be a little more practical .....
I use to keep a kookaburra (Not a live one (Thought i might add to the dry humor on this thread)) on my desk at work.
In our myth....you can carry ur wallet emptied. You need to have some notes (in any currency) in there
I don't need to keep more than a gram of silver in my pocket as a reminder that tomorrow that gram will make me very wealthy when silver goes to da moon. .
I have a PM 1oz croc, I keep in my bag that I take to work, I look at it often when im getting things out.
Often have some little gold nuggets for show and tell. The average person can understand and appreciate the intrinsic value of them and you can handle them with minimal wear and tear issues. Easier than trying to get someones head around 50s or other coins re value/worth.
