Price paid by legal value against the offer?

If I buy a 2007 American Buffalo Gold Coin for $ 889 and the value of legal tender is $ 50, what I get when I sell? Could be worth $ 50 when I use it in a store?

If desired, you can use for $ 50 I think, but if gold is solid, then you could have it and you will be able to sell at the price of gold and a piece of collection that will be even more. Just for example, we received the gold in the mine, I work to be sure. Were valued at $ 550 each for weighing gold, while the involvement of collectors has sent nearly 650 people care to get their hands on these gold coins.
