What is a pure gold dollar from France and in the yr 1888 worth?

Answer 1

If it is 24kt, it's not a real US dollar as they are only 90% pure (21.6kt) gold. If it is a US dollar, we need to know a lot more than just which century it was minted before we can even suggest a value. Year, mintmark, and condition according to ANA grading standards would be a good start. Ok. Now you've changed the question, but we still don't have enough information. But if it is French, it's not a dollar, and it's still not PURE gold, only 90%. Looking through the Standard Catalog of World Coins, 1801-1900, I SUSPECT you may have a 20 Franc coin (no gold French coins are shown for that time with a denomination of 1). Unless this coin shows absolutely no wear or damage, it will be valued for its bullion content. At the present spot price of $588, this would be about $120. However, since 1888 had a very small mintage, this year will retain more of its value than more commonly found dates will if the price of gold falls back below $500.
