Not that I could afford either, but if I had more than 400 dollars burning in my pocket, which would be better? A 5 gram bar with anti counterfeit features on the back of it from sunshine mint, or a fractional gold rooster from the french mint produced in the late 19th century. I wonder, doesn't the 20 francs gold coin have a little bit more gold, or far more than the 5 gram bar.
The 20 francs has 0.1867 troy ounces (5.807 g) There are fakes. 5 gram bar with anti counterfeit features probably safer as far as counterfeit measures. Buy what you like.
