What is the value of a 1987 constitutional 2 coin set with silver dollar and gold five dollar coin?

The 1987 U.S. Constitution Bicentennial 2 coin set comes with almost 1 oz of silver and nearly 1/4 oz of gold. The previous answer of $15-30 was completely incorrect. 1oz of silver has a current spot price of $28 and gold $1600, meaning the set is worth approximately $428 at spot. As the items are U.S. Mint commemorative coins, they may have additional collector value to a purchaser as well.
