According to the article, these will be available in the US next year.

Yummy! That's even better than Hanukkah gelt.

Now, how do you test those 1g bits for authenticity?

With a touchstone ? For a 1g bar, it will be enough as it cannot be filled with, say, tungsten.

I'd rather use 1/10 ounce coins, considering 3 grams = 1/10 of an ounce and the coins are more universally understood and accepted.

However, the spread on 1/10 ounce coins is huge (offhand it's around 15%)... if the spread on these bars was closer to spot, then it might be interesting. Otherwise, just get a credit card shaped plastic sleeve that can hold 1/10 ounce gold coins 5 across and 3 down (15 total for nearly 50 grams).
