Gold and silver

[drwelfare]

I used to keep a lot of silver (US coins) my dad stole it so I don't have a reserve now.

I'll trade you this tiny piece of gold for a loaf of bread, what do you say? Just let me shave it off my bar and weigh it out...

That isn't why it is practical to buy huge bars. Besides I am sure if one was stupid enough to resell their gold ... for bread, they would mix it with nickel or melt it into their own currency for smaller/cheaper rounds.
