Remember? Full moon was January 1st, now again on the 31st. And none in February! Also known as a blue moon.
What that has to do with the new Sacajawea dollar coin, I have no idea. Why not visit the U.S. Mint; maybe they know.
The designs are narrowed down to 7 finalists: 3 heads and 4 tails (does this mean the coin will be "loaded"?) I like these two best; visit the mint and see what you think of the others.
How Do I?
