This is the 10th Anniversary pack, which was released for free in the USA. The CD has music from Sonic games, and the booklet has a breif history with photos. The cover is quite fancy, and well-embossed. The coin is real metal. (Note that the photo does not show an actual coin, the real one is more chrome-gold) These could be difficult to find at times, and some stores only had them on pre-order. Best Buy was known to have a good supply. This is a truly nice collector's item.
