Collectible Cheerios Dollars

In 2000, when the [Sacagawea dollar] coin was introduced, 5500 of them were given away in boxes of Cheerios as a promotion. Turns out that these Cheerios Dollars were slightly different than all the other Sacagawea Dollars. The tail feathers of the eagle on the reverse side of the coin had more details than the normal coin, and this made them more valuable. However, most of these Cheeries Dollars disappeared into circulation, and only around 70 of them have ever been found.
