Copper Bullion

Can you spend a $500 bullion bar?
My aunt gave me a $500 bullion bar, 1 troy oz. of copper…can I spend this? It’s brand new she said. What’s it’s worth/value? If any…
No bullion bar has a dollar, or other unit of currency, denomination stamped into it. Only the weight and fineness of the bullion, and, perhaps, the maker. And, if it’s an art bar, some kind of artistic design. So I have no idea what you’re talking about re: $500.
To top it off, one troy ounce of copper is not very much copper. Roughly 29 cents worth of copper. Art bars can have extra collector value, but no bullion bar has a face value like a coin does. It has trade value, which is different. That trade value will vary, depending on what the two parties to the trade decide it is. For example, if you went into a store to try to buy a stick of gum priced at 25 cents, had no money, and produced one Troy ounce of copper, and said, ‘This here has 29 cents of copper.’, not only would you not get four cents in change, you would probably get laughed out of the store.
So you can’t spend it. What you have is meant to be a small collector’s item, not true bullion.
