I will instruct them to consider each ounce of silver to equate to a half-tank of gas, which is a good approximation and a good way for them to make reasonable barter deals when the bottom falls out from under the greenback.
Good choice on the silver. Duke, if you have not already, look into the 1 ounce pre-scored ‘divisible’ bars. You might find that style to your liking as it gives a lot more barter room for the holder. (Sometime only maybe a 1/4 or 1/2 ounce piece might be agreeable to your seller depending on your transaction).
What’s to stop them from selling that silver the next day. And buying apps or smokes or booze or dope?
