I found a link that tells you the gold value of various US gold coins based on the current price. No if I can only find the info on the US $5 Commemorative Gold coins and the $10 Commemorative Gold coins. Anyone know? (I think the $5 are 1/4 oz and the $10 are 1/2 oz).
Gold Coin Value CalculatorArt,
The modern commemorative half eagles and eagles issued by the mint were minted to the same standard as the old coins, so a $10 commem like the Olympic or First Flight contains 0.48375 troy ounce of gold, and all the commemorative $5 contain 0.241875 troy ounce of gold. The only exception to this is the bimetallic $10 commem for the Library of Congress issued in 2000, and I have no idea how much gold or platinum is in that one.
That link is very helpful, I just wish they had more foreign issues, particularly Mexican gold.
